The Steam Deck‘s internal drive fills up fast once you start installing modern AAA titles, and Valve’s own storage math hasn’t changed since the 2022 launch: a 60GB open-world game still eats a meaningful chunk of a 256GB tier in a single install. The fix most owners land on is swapping the internal NVMe module for something bigger, and as of October 21, 2026, that is still a supported, well-documented repair rather than a warranty-voiding gamble. This guide walks through the full process on both the original Steam Deck LCD and the Steam Deck OLED, using the parts Valve’s repair partner iFixit currently lists for the job.
Before touching a screwdriver, it helps to know where the hardware actually stands this month. Valve has not announced a Steam Deck 2, though The Verge reported in early October 2026 that AMD’s unreleased “Gainsborough” chip is the silicon most often linked to Valve’s next handheld. The original Steam Deck LCD is no longer sold new, but Valve continues shipping SteamOS updates to it, and iFixit continues selling replacement batteries and drives for it. The Steam Deck OLED remains the current retail model, and it is the one this guide treats as the baseline for assembly steps, though the LCD disassembly process is nearly identical.

Why Upgrade Your Steam Deck’s SSD in 2026
The timing also happens to line up with a broader storage squeeze. Memory and flash prices have been climbing across the PC market through the back half of 2026. If you have been waiting to upgrade, prices are trending in the wrong direction, which is itself a reason to lock in a purchase rather than wait.
Valve’s own hardware team has been candid that this isn’t an officially encouraged repair. In the company’s teardown video covering Steam Deck’s internals, Valve put it plainly: “We don’t recommend replacing the included drive,” adding later that “what we do recommend for increasing your storage capacity is the handy micro SD card slot.” That caution is worth taking seriously, but it doesn’t mean the swap is unsafe when done carefully with the right part. Valve’s own warning continues: “An off-the-shelf SSD can draw more power than the original drive, which could cause overheating and reduced battery life”, which is exactly why this guide sticks to a drive Valve’s repair partner has already qualified for the Deck rather than whatever NVMe stick happens to be cheapest.
It’s also worth understanding why Valve frames the microSD slot as its preferred answer even though most owners who’ve tried both say an internal NVMe swap feels completely different in practice. The microSD slot on both Steam Deck generations runs over a much slower bus than the internal M.2 socket, so while it’s an easy, tool-free way to add bulk storage for less frequently played titles, game load times and shader-compilation steps are noticeably slower from a card compared to the internal drive. For a primary game library you boot into daily, the internal NVMe swap remains the only way to get both the capacity and the speed of the factory drive, which is the entire reason this upgrade keeps showing up at the top of Steam Deck ownership guides years after launch.
Steam Deck LCD vs Steam Deck OLED: What’s Inside Each Model
The two Steam Deck generations share the same general internal layout, but the OLED model changed enough that it’s worth understanding the differences before you order parts or tools. According to Valve’s own OLED product page, the OLED model has “30-50% more battery life,” thanks to a bigger battery and a more power-efficient AMD APU, and it “runs cooler” thanks to a bigger fan and updated thermals. The screen’s active area also grew to 7.4 inches from 7.0 inches, Bluetooth jumped to version 5.3 with support for aptX HD and aptX low-latency codecs, and total system weight dropped to roughly 640g, about 5% lighter than the original LCD unit. Resume-from-sleep time improved by around 30% as well.
None of those changes affect the SSD swap procedure in a way that matters for storage capacity, but they do change screw patterns, shell clips, and battery connector routing slightly. iFixit’s parts catalog treats the two models as distinct product pages, Steam Deck LCD Storage and Steam Deck OLED Storage are separate listings, specifically because the disassembly sequence differs enough to warrant separate guides. If you own the OLED model, follow OLED-specific teardown photos for the shell-opening step; the SSD removal and installation steps described later in this guide are otherwise the same across both generations, since both use the same M.2 2230 form factor.
One more wrinkle worth flagging: Valve’s October 21, 2026 stock warning noted that Steam Deck OLED units could see intermittent regional shortages tied to memory and storage component supply constraints. If you’re planning this upgrade around a newly purchased unit, check availability before committing to a specific storage tier purchase plan, since swapping out a brand-new unit’s drive the same week you buy it is an unusual way to work around a stock gap.
Prerequisites and Compatibility Checklist
Gather everything below before you start. Running out of a tool or part halfway through disassembly with an open Steam Deck shell and a disconnected battery sitting on your desk is the single most common way this job goes from a 45-minute task to an overnight ordeal.
- Replacement SSD: An M.2 2230 PCIe 4.0 NVMe drive. This guide uses the Crucial P310, available as the 1TB model (CT1000P310SSD2) or 2TB model (CT2000P310SSD2), both rated up to 7,100 MB/s sequential read.
- Repair toolkit: A Torx-compatible driver set, plastic prying tools, and an anti-static wrist strap. iFixit sells a dedicated Steam Deck Toolkit for €17.95.
- Replacement SSD foil cover: iFixit lists a foil cover compatible with both Steam Deck LCD and Steam Deck OLED at $3.99 (€3.95), buy a spare since the factory one can tear during removal.
- A USB flash drive of at least 16GB, formatted FAT32, for the SteamOS recovery image.
- A second computer with internet access to download the recovery image and flash it to the USB drive.
- Stable Wi-Fi or Ethernet for re-downloading your Steam library after the swap, since a drive replacement wipes existing game data on the old module.
- 30–60 minutes of uninterrupted time. The physical swap itself takes roughly 15–20 minutes; recovery flashing and reboot cycles account for the rest.
A compatibility note worth double-checking: community upgrade guidance consistently states that only the M.2 2230 physical form factor fits inside the Steam Deck’s internal slot. A standard desktop M.2 2280 drive, the much more common consumer size, will not physically fit, no matter how good its specs look on paper. Always confirm “2230” appears in the product name before buying; Crucial also sells P310 drives in 2280 format for laptops and desktops, and it’s an easy mix-up to make while shopping.
Buying Used? What to Check Before You Upgrade a Secondhand Deck
A fair number of people doing this upgrade aren’t working on their original unit, they picked up a used Steam Deck specifically because a drive swap makes a lower storage tier a non-issue at resale prices. If that’s you, a few extra checks before you even order a replacement SSD will save you from discovering a problem mid-repair. First, boot the unit and check Settings > System for the current SteamOS build; if it’s running something noticeably old, update it over Wi-Fi before doing anything else, since an outdated recovery partition can complicate the later reinstall step.
Second, inspect the back shell for prior disassembly. Mismatched or stripped screws, a slightly misaligned shell seam, or a foil cover that looks newer than the rest of the unit are all signs someone already opened the case, not necessarily a dealbreaker, but worth knowing before you start, since a previous repair that wasn’t done carefully can leave a ribbon cable slightly loose even if the device currently works fine. Third, run a quick battery health check through desktop mode, since a Deck that’s been heavily used tends to need a battery replacement around the same time storage starts feeling cramped, and it’s far more efficient to handle both repairs in the same session rather than opening the shell twice.
Step 1–2: Back Up Your Library and Check Current Storage
Open Steam’s desktop mode (hold the Power button, choose “Switch to Desktop”) and launch a terminal (Konsole). First, confirm what drive is currently installed and how it’s partitioned, this becomes your reference point for comparing against the new drive later.
lsblk -d -o NAME,SIZE,MODEL,TRAN
nvme listThis should return your current drive’s model string and interface (NVMe), along with its reported capacity. Note this output or screenshot it, it’s the quickest way to confirm, after reassembly, that the system actually detected the new module and isn’t silently falling back to booting from microSD.
Next, back up anything that doesn’t already live in Steam Cloud: save files for games without cloud sync, custom controller profiles, emulator configurations, and any screenshots or video captures stored locally. The cleanest approach is copying everything to an external drive via desktop mode’s file manager, or using rsync if you’re comfortable with a terminal:
rsync -avh --progress /home/deck/.local/share/Steam/userdata/ /run/media/deck/BACKUP/userdata/
rsync -avh --progress /home/deck/.steam/steam/userdata/ /run/media/deck/BACKUP/userdata-legacy/Games themselves don’t need backing up since they re-download from Steam; what you’re protecting here is saves and settings that aren’t guaranteed to sync automatically.
Step 3–4: Gather Tools and Choose a Replacement SSD
With backups confirmed, decide on capacity. The table below lines up the current iFixit-listed options as of October 20–21, 2026, across its US, UK, and EU storefronts, alongside the Micron alternative iFixit also carries.
| Drive | Capacity | Interface | iFixit US | iFixit UK | iFixit EU (Spain) |
|---|---|---|---|---|---|
| Crucial P310 (CT1000P310SSD2) | 1TB | PCIe 4.0 NVMe, M.2 2230 | Listed as part of $161.99 kit | £173.99 | €199.95 |
| Crucial P310 (CT2000P310SSD2) | 2TB | PCIe 4.0 NVMe, M.2 2230 | $308.73 (Newegg, Oct 20) | – | – |
| Micron 2500 NVMe | Varies | PCIe Gen4, M.2 2230 | $156.99 | – | – |
| Steam Deck SSD: Upgrade Kit (drive + tools) | 1TB | PCIe 4.0 NVMe, M.2 2230 | $161.99 | £177.99 | €204.95 |
| Steam Deck Toolkit (tools only) | – | – | – | – | €17.95 |
| SSD foil cover (LCD & OLED) | – | – | $3.99 | – | €3.95 |
Both Crucial P310 capacities are rated for sequential reads up to 7,100 MB/s, well beyond what the Steam Deck’s PCIe lanes will fully exploit, so the practical difference between the two is capacity and price, not real-world speed. If you’re on a budget and mainly need headroom over a stock 256GB or 512GB drive, 1TB covers most libraries comfortably; if you run several large open-world titles side by side without uninstalling, the 2TB option avoids the juggling.
Buy the “Upgrade Kit” version if this is your first repair of this kind, it bundles the SSD with the Torx driver, prying tools, and a replacement foil cover in one purchase, which is cheaper and simpler than sourcing each piece separately. If you already own a repair toolkit from a previous phone or console job, the SSD-only listing saves a few dollars.
Step 5–6: Update SteamOS and Create a Recovery Drive
On your second computer, download the current SteamOS recovery image from Valve’s Steam Deck support resources and flash it to your 16GB+ USB drive using a tool like balenaEtcher. If you prefer a command-line approach on Linux or inside SteamOS desktop mode itself, the equivalent `dd` command looks like this (replace `/dev/sdX` with your actual USB device, confirmed first via `lsblk`):
lsblk
sudo dd if=steamdeck-recovery-4.img of=/dev/sdX bs=4M status=progress conv=fsync
syncDouble- and triple-check the device path before running this command, `dd` will silently overwrite whatever device you point it at, including your main system drive if you get the letter wrong. Label the USB drive physically once it’s flashed so you don’t mix it up later.
Step 7–9: Power Down, Open the Shell, and Remove the Old Drive
Fully power off the Steam Deck, not sleep, a full shutdown, and disconnect any charger. Work on a clean, static-free, well-lit surface. Remove the eight Torx screws from the back shell (the exact count and screw lengths differ slightly between LCD and OLED models; iFixit’s model-specific guide photos show which screws are shorter so you don’t mismatch them on reassembly). Use the plastic prying tools to separate the back shell from the front, working around the edge rather than forcing any single point.
Handling the Battery Connector Safely
Once the shell is open, disconnect the battery connector before touching anything else. This is a safety step, not an optional one: working on a board that’s still electrically live from the battery risks shorting a component if a tool slips. The connector is small and uses a simple pull-up motion rather than a latch, use a plastic spudger rather than metal tweezers to avoid scratching the board or bridging adjacent pins.
With the battery disconnected, locate the NVMe module. It sits under a small foil shield secured by adhesive and, per current repair documentation, a single retaining screw. Peel back the foil carefully, this is the part most likely to tear, which is why buying a spare foil cover ahead of time is worth the few dollars. Remove the retaining screw, and the M.2 2230 drive will sit at a slight angle; gently pull it free from its slot.
Step 10–11: Install the New NVMe Drive and Reassemble
Line up the new Crucial P310 module’s gold contacts with the slot, insert at the same angle the old drive came out at, and press down gently until it sits flush. Replace the single retaining screw, don’t overtighten, since M.2 screws are small and strip easily. Apply the new foil cover if the old one tore, pressing it down firmly around the drive to maintain the same thermal and ESD shielding the factory part provided.
Reconnect the battery connector, confirming it clicks or seats fully before closing anything up. This is a good moment to do a quick power-on test with the shell still open: press the power button briefly to confirm the device boots to a logo screen before you commit to closing the case. If nothing happens, recheck the battery connector before assuming the drive itself is at fault.
Once confirmed, power off again, snap the front and back shells back together, and reinstall all eight screws in their original positions, this is where keeping track of screw lengths during disassembly pays off, since a screw that’s too long in the wrong hole can crack the plastic shell or damage a component underneath.
Step 12–13: Flash the Recovery Image and Restore Your Library
Plug in your recovery USB drive, then hold Volume Down and press the Power button to enter the boot menu, selecting the USB device. The recovery environment will walk you through reinstalling SteamOS onto the new, blank drive. This is the step that turns a bare NVMe module into a bootable Steam Deck, and it typically takes 10–15 minutes depending on USB drive speed.
After SteamOS finishes installing and the system reboots into the familiar Deck interface, sign back into your Steam account and let it resume download of your library. This is also when you restore the userdata backup from Step 1–2 if any of it isn’t already covered by Steam Cloud:
rsync -avh --progress /run/media/deck/BACKUP/userdata/ /home/deck/.local/share/Steam/userdata/
chmod -R u+rwX /home/deck/.local/share/Steam/userdata/Give the chmod command a moment to run on larger backups, and don’t interrupt the Steam client while it’s still indexing the restored userdata folder, closing it mid-scan is a common way to end up with saves that show in the file system but don’t appear inside the game itself.
Verifying the New Drive: Benchmarks and Health Checks
Once everything is restored, confirm the new drive is actually operating at full speed rather than falling back to a degraded PCIe link mode, this can happen if the module isn’t fully seated. Back in desktop mode’s terminal, run:
sudo nvme smart-log /dev/nvme0n1
sudo fio --name=seqread --rw=read --bs=1M --size=2G --numjobs=1 --filename=/home/deck/testfileThe `smart-log` output should show a healthy temperature reading and zero (or very low) media error counts; the `fio` sequential read test gives you a rough real-world throughput figure you can sanity-check against the drive’s rated 7,100 MB/s ceiling (expect noticeably less in practice, since the Deck’s own PCIe implementation and OS overhead cap real-world numbers well under the drive’s maximum spec, the test is about confirming the drive responds and performs consistently, not hitting the rated peak).
Reading NVMe SMART Data
Keep an eye on three fields in particular over the following weeks: percentage used (drive wear), temperature, and critical warning flags. A fresh Crucial P310 should report very little wear and a critical warning value of 0. If temperature readings climb unusually high during extended play sessions, double-check that the foil shield is seated correctly, it plays a role in directing airflow and preventing the drive from running hotter than Valve’s original thermal design intended.
Common Pitfalls When Upgrading Steam Deck Storage
- Buying the wrong form factor. M.2 2280 is the far more common consumer size and will not physically fit. Confirm “2230” is in the product listing before ordering.
- Skipping the SteamOS update before opening the shell. Doing the physical swap first, then discovering your recovery image is out of date with your last-known SteamOS build, adds an avoidable extra reboot cycle.
- Working without discharging static. Skipping the anti-static strap on a dry day is a common way to damage the NVMe controller before it’s even installed.
- Forgetting to disconnect the battery. Prying at board-level components while the battery is still connected is the single riskiest moment in the whole process.
- Buying an unqualified off-the-shelf NVMe stick to save money. Valve’s own warning about higher power draw and potential overheating on untested drives is specifically about this scenario, stick to drives the Deck repair ecosystem has already validated.
- Overtightening the M.2 retaining screw. It’s small and strips easily; snug is enough.
- Mismatching screw lengths on reassembly. Steam Deck uses different screw lengths in different positions; a longer screw in the wrong hole can crack the shell or damage internal components.
- Assuming all storage tiers use the same swap procedure. If you’re not certain your unit has a removable NVMe module versus soldered storage, check Settings > System in SteamOS first rather than assuming based on capacity alone.
Troubleshooting Guide: 8 Issues and Fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Device won’t power on after reassembly | Battery connector not fully seated | Reopen the shell and confirm the connector clicks into place before closing again |
| NVMe drive not detected in recovery environment | Drive not fully seated, or retaining screw missing | Reopen and reseat the module; confirm the screw is present and snug, not just resting in place |
| Recovery USB won’t boot | Image flashed incorrectly or wrong USB device targeted | Reflash using balenaEtcher or re-run the dd command, verifying the device path with lsblk first |
| SteamOS stuck on logo screen after install | Incomplete recovery flash, or an interrupted first-boot process | Force a restart via Power + Volume Down, then re-run the recovery installer from the USB |
| Wi-Fi or Bluetooth stopped working after the swap | Antenna ribbon cable disturbed during disassembly | Reopen the shell and check that the Wi-Fi/Bluetooth ribbon cable near the shell edge is still fully seated |
| Battery won’t charge post-upgrade | Battery connector seated at an angle, or charging port cable disturbed | Recheck the battery connector seating; inspect the USB-C charging port ribbon for any pinching |
| Game library won’t sync after restore | Steam Cloud still indexing, or userdata restored to the wrong path | Give Steam a few minutes after login before launching games; confirm userdata was restored to /home/deck/.local/share/Steam/userdata/ |
| Drive runs hotter than expected under load | Foil shield not seated correctly, disrupting airflow | Reopen and confirm the foil cover sits flush and fully adhered around the module |
Advanced Tips: TRIM, Dual-Boot, and Capacity Planning
Once the drive is running reliably, a few extra steps keep it healthy and extract more value from the upgrade. First, confirm TRIM is enabled, since SteamOS’s underlying filesystem benefits from periodic TRIM passes to maintain NVMe write performance over time:
sudo fstrim -v /
sudo systemctl status fstrim.timerIf `fstrim.timer` isn’t active, enabling it ensures the drive gets a periodic trim pass automatically rather than relying on manual runs. TRIM matters more on a drive that’s been through a few months of install-and-uninstall cycles than it does on day one, but there’s no downside to confirming it’s active right after the swap rather than waiting for performance to visibly degrade before troubleshooting.
It’s also worth keeping the old drive rather than discarding it, even after a successful upgrade. A spare factory NVMe module, properly labeled, works as a known-good fallback if the replacement drive ever develops a fault, simply reverse the swap and you’re back on original hardware without waiting on a warranty claim or a reorder. Some owners also repurpose the old drive in an external M.2 enclosure for backups or as portable storage for a laptop, since a 256GB or 512GB PCIe module still has plenty of life left in it outside the Deck.
Second, if you’re considering a Windows dual-boot setup now that you have more room, allocate a dedicated partition during the recovery install rather than trying to resize later, resizing an active SteamOS partition after the fact is possible but adds risk for a job that’s otherwise straightforward. Third, on capacity planning: a 2TB drive comfortably holds a rotating library of a dozen or more modern titles without needing to uninstall anything mid-session, while a 1TB drive is still a major upgrade over any factory tier and costs meaningfully less given current NVMe pricing. Buy for the habit you actually have, if you tend to finish and uninstall games rather than keep a large rotating backlog, 1TB covers nearly everyone comfortably.
Finally, if you’re curious whether this same swap logic extends to Valve’s other current hardware: it doesn’t, at least not the same way. The Steam Frame VR headset, which replaces the Valve Index, uses 256GB or 1TB UFS storage with microSD expansion up to 2TB rather than a swappable NVMe module, a different repair profile entirely, and one iFixit’s own teardown flagged for battery glue and fan design rather than storage upgradeability.
How Much Storage Do You Actually Need
It’s worth running the numbers before settling on a capacity, since overbuying and underbuying both carry real costs right now given how much NVMe pricing has moved this year. A factory 256GB tier typically holds somewhere between four and eight modern AAA installs depending on genre, with open-world titles and anything built on an engine that ships uncompressed texture packs eating storage fastest. A 512GB tier roughly doubles that headroom, which is why it became the more popular factory configuration for owners who play more than a couple of active titles at a time.
Jumping to a 1TB Crucial P310 effectively matches or exceeds the largest factory tier Valve has ever shipped on the Deck, which is enough for most owners to stop thinking about storage entirely unless they’re also running a sizeable emulation library through RetroArch or similar front ends alongside their Steam catalog. The 2TB tier is really aimed at a narrower audience: people who keep a large rotating backlog installed rather than uninstalling finished games, or who use the Deck as a combined PC-gaming-and-emulation device where every freed-up gigabyte just gets filled by another ROM set. Given the price gap between the two capacities tracked in the table above, most owners are better served putting the savings from a 1TB drive toward a larger microSD card for secondary storage rather than stretching for 2TB on the internal module alone.
Complete Working Project: From Stock Drive to a 2TB Steam Deck
Put together, a full upgrade session looks like this from start to finish:
- Order the Crucial P310 2TB (CT2000P310SSD2) and, if you don’t already own one, the iFixit Steam Deck Toolkit.
- Flash a SteamOS recovery image to a 16GB+ USB drive on a second computer.
- Power off the Deck fully, open the shell with the Torx driver and prying tools, and disconnect the battery.
- Remove the old drive’s foil shield and retaining screw, then pull the stock module free.
- Insert the Crucial P310 2TB module, replace the retaining screw, and apply a fresh foil cover if needed.
- Reconnect the battery and do a quick power-on test with the shell still open.
- Close the shell and reinstall all eight screws in their original positions.
- Boot from the recovery USB and reinstall SteamOS onto the new drive.
- Sign into Steam, let the library begin redownloading, and restore userdata from backup.
- Run `nvme smart-log` and a quick `fio` sequential read test to confirm the drive is healthy and performing normally.
- Enable `fstrim.timer` if it isn’t already active.
- Reinstall your most-played titles first, confirm saves carried over correctly, and resume normal use.
Total elapsed time for most owners doing this for the first time runs 45–60 minutes, with the physical disassembly and reassembly taking the smallest share of that and the SteamOS recovery flash and library redownload taking the rest.
Frequently Asked Questions
Does upgrading the SSD void my Steam Deck’s warranty?
Valve has historically treated the Steam Deck as a user-serviceable device and sells official repair guides and parts through iFixit specifically to support this kind of upgrade, which is a different posture than consoles that explicitly void warranties for any disassembly. Still, Valve’s own messaging is that it doesn’t officially recommend replacing the internal drive, so if your unit is still under warranty and you’re worried about a specific claim, check Valve’s current terms before opening the shell.
Can I use any M.2 2230 NVMe drive, or does it have to be a Crucial P310?
The physical form factor requirement (M.2 2230, not the far more common 2280) is the hard constraint. The Crucial P310 is the drive currently sold through iFixit’s Steam Deck-specific listings and qualified for the device, which is why this guide centers on it, but other 2230 NVMe drives can work if they meet the Deck’s power draw tolerances, Valve’s own warning about off-the-shelf drives drawing more power and running hotter is the risk to weigh if you go outside a Deck-qualified option.
Will a bigger SSD improve load times or frame rates?
Not directly. The swap is about capacity, not performance, your CPU and GPU remain unchanged. Faster NVMe speeds can modestly shorten level-load times in games that are storage-bound, but it won’t change in-game frame rates.
Is there a Steam Deck 2 I should wait for instead?
No Steam Deck 2 has been released or officially announced. Reporting from The Verge in early October 2026 ties a possible next-generation Deck to AMD’s unreleased “Gainsborough” chip, and separate reports say Valve hasn’t settled on timing for a successor. Treat any Steam Deck 2 as a rumor, not a near-term purchase decision to plan around.
What’s the difference between the Steam Deck LCD and OLED disassembly process?
The core SSD swap steps are the same, but screw counts, shell clip positions, and some cable routing differ enough that iFixit publishes separate model-specific guides for each. Always confirm which model’s photos you’re following before removing screws.
Can I upgrade the 64GB base model the same way?
Check Settings > System in SteamOS first to confirm whether your specific unit has a removable NVMe module versus soldered storage before assuming the swap applies the same way across every storage tier Valve has sold.
Do I need to reinstall every game after the swap, or can I clone the old drive?
Valve’s recovery process installs a fresh SteamOS image rather than cloning, so games redownload from Steam’s servers. Save data and settings you backed up via rsync in Step 1–2 restore separately and don’t require redownloading.
How do I know if the new drive is actually faster than my old one?
Run `nvme smart-log` and an `fio` sequential read test after the swap, as covered in the verification section above, and compare the reported throughput against your drive’s rated speed and your prior experience with load times on the old module.
