Samsung has cut the price of its P9 Express microSDXC cards, the only memory cards the company markets as compatible with the Nintendo Switch 2, with Amazon listings on October 19, 2026 showing the 256GB model at $59.99 and the 512GB model at $99.99. Those prices sit well below Samsung’s own official list prices of $79.99 and $149.99, according to the company’s US product pages. For Switch 2 owners who have been watching the card’s price since its December 10, 2025 debut, the discount marks the first meaningful drop reflected across both Samsung’s listings and Amazon’s storefront on the same day.
The timing matters. Nintendo Switch 2 owners have spent most of 2026 dealing with console price hikes across Japan, Canada, and Europe and a growing gap between digital and physical game pricing, so a drop on the accessory side stands out. Samsung’s P9 Express line is also one of the few microSD products built specifically around the SD Express standard that the Switch 2 requires to hit its advertised load-time and game-install speeds, which makes the pricing move relevant well beyond a routine Amazon markdown.

What’s Actually on Sale: The 256GB and 512GB P9 Express Cards
Samsung sells the P9 Express microSDXC line in two capacities relevant to this story. The 256GB card carries model number MB-MK256T/AM, and the 512GB card carries model number MB-MK512T/AM. Samsung’s product documentation identifies both cards as compatible with the Nintendo Switch 2, positioning them squarely at the console’s storage-expansion market rather than as general-purpose cards repurposed for gaming.
Both cards carry a limited three-year warranty, according to the Samsung brochure listing their specifications. That warranty window is standard for Samsung’s consumer memory card lineup, but it’s worth noting for buyers comparing the P9 Express against older UHS-I cards that typically ship with similar coverage. The underlying hardware, however, is not the same generation of technology as a standard UHS-I card, which is the real story behind why these cards cost more than a typical microSD card for a phone or camera.
Official Samsung Pricing vs. the Discounted Amazon Listings
The gap between Samsung’s list pricing and what shoppers are actually paying on Amazon is the core of this story. Samsung’s own US product pages, dated December 10, 2025 with updates showing October 19, 2026, list the 256GB P9 Express at $79.99 and the 512GB version at $149.99. Amazon’s listings, also dated October 19, 2026, show the 256GB card at $59.99 (marked as a 25% savings) and the 512GB card at $99.99 (marked as a 33% savings). That works out to a $20 reduction on the smaller card and a $50 reduction on the larger one.
| Capacity | Model Number | Samsung List Price | Amazon Price (Oct. 19, 2026) | Listed Savings | Dollar Difference |
|---|---|---|---|---|---|
| 256GB | MB-MK256T/AM | $79.99 | $59.99 | 25% | $20 lower |
| 512GB | MB-MK512T/AM | $149.99 | $99.99 | 33% | $50 lower |
Reports on this pricing gap note that the 512GB card’s discount is proportionally larger than the 256GB card’s, which tracks with how retailers typically price higher-capacity storage more aggressively once a product has been on shelves for several months. Neither Samsung nor Amazon has published an explanation for the discount’s timing, so the reasoning behind it remains attributed to the listings themselves rather than any company statement.
Full Spec Sheet: What SD Express 800 MB/s Actually Means
The P9 Express line is built around the SD Express specification, which is the detail that separates it from the UHS-I cards most people are used to buying for phones and cameras. According to Samsung’s brochure, the card supports SD Express transfer speeds up to 800 MB/s, falls back to UHS-I speeds of 90 MB/s when used in older card readers, and relies on PCIe Gen3.0x1 and NVMe 1.3 as its underlying interface and protocol. The card is also built to the SD 7.1 specification and carries the U3, V30, and A1 speed classifications.
| Specification | Value |
|---|---|
| Card type | microSDXC |
| SD Express speed | Up to 800 MB/s |
| UHS-I fallback speed | 90 MB/s |
| Interface | PCIe Gen3.0x1 |
| Protocol | NVMe 1.3 |
| SD specification | SD 7.1 |
| Speed class | U3, V30, A1 |
| Warranty | Limited 3-year |
That PCIe-based architecture is the reason the P9 Express costs more than a conventional microSD card of the same capacity. A UHS-I card, the kind most people already own for a phone or a Steam Deck, tops out around 100 MB/s under ideal conditions. The P9 Express is engineered to push past that ceiling by nearly eight times when paired with a host device, like the Switch 2, that actually supports the SD Express standard. The catch, and the reason this matters for shoppers, is that the card only delivers that speed on hardware built to use it, which for handheld gaming today effectively means Nintendo’s newest console.
Why the Nintendo Switch 2 Needs an SD Express Card in the First Place
The original Nintendo Switch, and the Switch OLED model that followed it, both relied on standard UHS-I microSD cards for storage expansion. Game file sizes on those consoles rarely strained a 90 MB/s read speed, so the slower, cheaper card format was adequate for most owners. The Switch 2 changed that calculation by shipping with larger internal storage and a game library built around bigger file sizes, higher-resolution textures, and faster load expectations, all of which put more pressure on whatever storage card gets slotted into the console.
Nintendo’s decision to support SD Express on the Switch 2 is the reason Samsung built the P9 Express line around that same standard rather than shipping another conventional UHS-I card. It also explains why these cards sit at a noticeably higher price point than the microSD cards most shoppers are used to buying for a phone. A standard 256GB UHS-I card from a major brand often sells for well under $30, while the SD Express version aimed at the Switch 2 carries a list price nearly triple that, even after the discount reflected on Amazon.
That price premium has made storage one of the most-discussed ongoing costs of owning a Switch 2, alongside the console’s own pricing swings. It’s a conversation that overlaps with broader storage debates playing out across the hardware market, including the gap in transfer speeds between Thunderbolt 5, USB4, and USB 3.2 portable SSDs, where interface bottlenecks produce the same kind of real-world speed gaps that separate SD Express from UHS-I in the microSD world.
A Timeline: From December 2025 Launch to the October 2026 Price Cut
Samsung’s US product pages for the P9 Express cards are dated December 10, 2025, placing the card’s original listing roughly ten months before the discount visible on Amazon today. The Samsung pages themselves show an update timestamp of October 19, 2026, the same date reflected on the Amazon listings, which suggests the pricing change registered across both platforms within the same reporting window rather than drifting apart over separate update cycles.
What isn’t confirmed in Samsung’s own product records is any claim that the card held a higher price for months before this cut, or that an earlier price point reached figures as high as $200 or $185. Those specific numbers appear only in secondary reporting rather than in Samsung’s or Amazon’s published listings, so they should be treated as unverified rather than as part of the card’s confirmed pricing history. What is confirmed is the side-by-side gap between Samsung’s $79.99/$149.99 list prices and Amazon’s $59.99/$99.99 discounted prices, both dated the same day.
Market Impact: What a Storage Discount Means for Switch 2 Accessory Demand
Storage has quietly become one of the more expensive parts of owning a Switch 2. The console’s price itself has already climbed in multiple regions this year, and reports on Nintendo’s pricing structure have highlighted a widening gap between digital and physical game costs as well. A discount on the one microSD card Samsung explicitly markets for the console gives price-sensitive buyers, including people who held off on expanding storage while console and game prices climbed, a lower-cost entry point into faster storage than they had earlier in 2026.
For retailers and accessory makers, a price move like this one on a flagship-compatible card tends to ripple into how the broader storage accessory market gets priced around a console’s second full year on shelves. Samsung’s pricing choices on the P9 Express sit alongside the company’s other recent storage announcements, including the SanDisk NAS 800 SSD launch that pushed sequential speeds to 14.9GB/s at the top of its lineup, a reminder that Samsung-owned and Samsung-adjacent storage brands have been active on multiple fronts of the market throughout 2026.
The Thin Competitive Field Around SD Express Cards
One detail that stands out in this story is how few companies are actually competing with Samsung in the SD Express microSD space built for the Switch 2. Most of the major microSD brands that dominate the broader card market still center their lineups on UHS-I and UHS-II products, formats that remain cheaper to manufacture and sufficient for phones, cameras, and the original Switch. SD Express requires a different controller architecture built around PCIe and NVMe, the same underlying technologies found in full-size SSDs, which raises the manufacturing bar in a way that has kept the field narrow so far.
That narrow field gives Samsung more room to set pricing on the P9 Express than it would have in a crowded microSD market. It also means the discount reflected on Amazon today functions less like a reaction to a rival’s price cut and more like a standard markdown cycle on a product that has had the Switch 2 compatibility market mostly to itself since its December 2025 debut. Buyers comparing storage options more broadly, including external drives rather than cards slotted into the console itself, can find more context in coverage of how DIY NVMe enclosures stack up against pre-built portable SSDs on raw speed.
How the Discount Breaks Down Across Both Capacities
Breaking the two discounts down side by side shows a consistent pattern: the higher-capacity card is getting the deeper percentage cut. The 512GB card’s 33% discount against its $149.99 list price works out to $50 in savings, while the 256GB card’s 25% discount against its $79.99 list price comes to $20. On a per-gigabyte basis, that gap narrows the price difference between the two capacities when buying at the Amazon price rather than Samsung’s own list price, making the 512GB card a comparatively better value at the discounted rate than it was at full price.
That per-gigabyte shift is relevant for Switch 2 owners trying to decide between the two capacities. At Samsung’s list prices, doubling the capacity from 256GB to 512GB costs an additional $70. At Amazon’s discounted prices, that same capacity jump costs an additional $40, a meaningfully smaller premium for buyers who were on the fence about springing for the larger card to avoid managing game installs more actively.
The Switch 2 Storage Problem This Card Is Built to Solve
Switch 2 owners have spent much of 2026 juggling storage management in a way earlier Switch generations rarely demanded, largely because newer titles ship with substantially larger install sizes. That pressure sits alongside Nintendo’s own pricing moves on physical and digital games, which reporting has shown carry a real cost gap depending on format. A faster, higher-capacity card doesn’t change those game prices, but it does reduce how often owners have to delete and redownload titles to make room for new ones, which is the practical daily annoyance driving demand for cards like the P9 Express in the first place.
It’s also worth noting that this storage pressure compounds with other Switch 2 ownership costs that have been in the news throughout 2026, from regional console price increases to shifts in how digital and physical titles are priced relative to each other. A cheaper path to 512GB of fast, SD Express-capable storage doesn’t offset those other costs, but it does remove one variable from the broader cost-of-ownership conversation Switch 2 buyers have been having all year.
Analysis: Why Samsung Is Moving Price Now
Neither Samsung nor Amazon has published a stated reason for today’s pricing, so any explanation has to stay in the realm of reasonable inference rather than confirmed fact. What is observable is the calendar: the P9 Express has now been on the market for roughly ten months, which is a fairly typical point in a consumer electronics product’s lifecycle for a retailer to start discounting against the manufacturer’s list price, particularly once a product has built up enough sales history and customer reviews for a retailer like Amazon to price it more aggressively.
It’s also plausible that broader memory pricing trends are playing a role, given how active the memory market has been throughout 2026 across multiple product categories. Samsung and its storage-adjacent divisions have made several pricing and product announcements this year, and a retailer-side discount on an already-established card is consistent with a company managing a broader portfolio rather than reacting to any single competitive threat in the narrow SD Express microSD space.
What This Means for Switch 2 Owners Weighing an Upgrade
For anyone who has been holding off on buying a microSD card for their Switch 2 because the P9 Express sat at Samsung’s $79.99 or $149.99 list price, today’s Amazon pricing closes a meaningful amount of that gap. The 256GB card at $59.99 brings the entry point for SD Express storage closer to what shoppers are used to paying for premium UHS-I cards, while the 512GB card at $99.99 undercuts the psychological $100 mark that often influences purchasing decisions on storage products.
Buyers should still confirm they’re purchasing the correct model number, MB-MK256T/AM for the 256GB card or MB-MK512T/AM for the 512GB card, since Samsung sells other microSD lines that are not built around the SD Express standard and will not deliver the same speed benefit on a Switch 2. The compatibility claim and the speed benefit are specific to the P9 Express line, not to Samsung microSD cards generally.
Predictions: Where Switch 2 Storage Pricing Goes From Here
- Expect more retailer-side discounts on the P9 Express line as the card approaches its first full year on the market in December 2026, following the same pattern seen with other storage products as they age past initial launch pricing.
- Watch for additional manufacturers to enter the SD Express microSD space over the next year, given that Nintendo’s SD Express support on the Switch 2 creates a dedicated demand pool that has so far been served by a narrow field of products.
- The gap between Samsung’s list prices and street prices on major retailers is likely to widen further around the holiday shopping season, a period when storage accessories for gaming consoles typically see some of their steepest annual discounts.
- 512GB and higher capacities should continue seeing proportionally larger discounts than smaller capacities, consistent with the pattern already visible in today’s 33% versus 25% discount split between the two P9 Express sizes.
- Storage pricing will likely remain a recurring theme in Switch 2 coverage through the rest of 2026, running parallel to the console and game pricing stories that have already shaped much of this year’s Switch 2 news cycle.
How This Fits Into Nintendo’s Broader 2026 Pricing Story
Today’s microSD discount doesn’t exist in isolation. It lands in the same year Nintendo raised Switch 2 console prices across multiple regions, including the jump to ¥59,980 reported in Japan, and in the same year reporting highlighted a real dollar gap between digital and physical game pricing on the platform. Viewed against that backdrop, a cheaper path to fast storage reads less like an isolated Amazon markdown and more like one data point in a year where nearly every cost associated with owning a Switch 2, from the console itself to the games and now the storage that holds them, has been in flux.
For shoppers tracking Switch 2 total cost of ownership, the P9 Express discount is one of the few cost reductions in an otherwise upward pricing trend this year. It’s a detail worth factoring into any broader calculation of what the console actually costs to own and keep stocked with games heading into the 2026 holiday season, alongside recent Switch 2 software news such as the Witcher 3 Switch 2 patch that improved image quality on the platform, a reminder that both software and storage demands on the console keep climbing even as some accessory prices head the other way.
