[src1, src3, src9] ## Summary The defining fact of the microSD market in August 2026 is not price but **availability**. Samsung's entire UHS-I consumer line — EVO Select, PRO Plus and PRO Ultimate — is out of stock at 256GB on both Amazon and Samsung's own US store, and the Lexar Professional Silver Plus 256GB single card is unavailable too (only a 2-pack remains at $134.99, or $67.50 per card). The practical consequence is that **SanDisk is currently the only brand with its full 256GB UHS-I range reliably in stock**, which is why the top pick has moved from the Lexar Silver Plus to the SanDisk Extreme 256GB at $71.98 (190/130 MB/s, V30 + A2). Where a Samsung card is still the right product on the merits, this card links to Samsung's official product page rather than a marketplace listing — third-party Amazon sellers are currently asking $99.95–$219.90 for cards whose MSRPs are $72.99–$99.99. [src1, src3, src10, src11] The cause is the AI-driven NAND shortage. Tom's Hardware measured a median 124% price increase across memory cards and flash drives versus 2025, with some SKUs up 261%; analysts now expect no meaningful relief until late 2027, when new fabs come online [src10, src11]. The visible effect on this card is that **the sub-$30 256GB tier no longer exists**. The cheapest 256GB card in this lineup is the SanDisk High Endurance at $65.99, and that is an endurance-tuned card with modest 100/40 MB/s speeds — for general-purpose use the honest budget answer is now the SanDisk Extreme at ~$71.98, roughly $0.28/GB. Samsung's PRO Endurance 256GB has been hit hardest of all, climbing from ~$106 to $149.99 (+41%) in five weeks. [src1, src7, src10] The microSD Express tier has been comparatively stable. SanDisk's microSD Express 256GB is $74.79 and Samsung's P9 Express 256GB is $79.25 — the SanDisk remains both cheaper and faster on paper (880/650 vs 800/600 MB/s), though real-world Switch 2 load-time differences between Express cards are imperceptible. The Lexar Play PRO 1TB holds at $349.99. The Switch 2 is still the only mainstream consumer device that supports microSD Express, so these cards fall back to UHS-I speeds (~100 MB/s) in any other device — buy one only if you own a Switch 2.

Capacity is the SKU — every price below is for the capacity named in its own row, and $/GB is computed from that capacity. | Model | Price | Capacity priced | $/GB | Read / Write | Speed Class | Stock (Aug 2026) | Best For | Buy | |---|---|---|---|---|---|---|---|---| | SanDisk Extreme | ~$71.98 | 256GB | $0.28 | 190 / 130 MB/s | UHS-I, U3, V30, A2 | In stock | Best overall UHS-I | [Check price](https://knowledgelib.io/go/sandisk-extreme-microsd-256) | | SanDisk Extreme PRO | ~$72.25 | 256GB | $0.28 | 200 / 140 MB/s | UHS-I, U3, V30, A2 | Low stock | 4K video production | [Check price](https://knowledgelib.io/go/sandisk-extreme-pro-microsd-256) | | SanDisk High Endurance | ~$65.99 | 256GB | $0.26 | 100 / 40 MB/s | UHS-I, C10, U3, V30 | In stock | Cheapest 256GB; budget dashcam | [Check price](https://knowledgelib.io/go/sandisk-high-endurance-256) | | Kingston Canvas Go!

Its V30 rating guarantees the sustained 30 MB/s minimum write required for 4K video without dropped frames, the A2 rating covers app and game random-IOPS use on a Steam Deck or Raspberry Pi, and the card is temperature, water, shock and x-ray proof. It is the safe default when you do not know the target device's requirements. [src1, src3, src4] ### Best for Drones & Action Cameras: SanDisk Extreme 256GB (~$71.98) — [Check price](https://knowledgelib.io/go/sandisk-extreme-microsd-256) The same card is also the long-standing default for DJI drones, GoPro cameras and Insta360 devices. SanDisk's QuickFlow Technology helps with burst-mode shooting, and the V30 class is the spec that actually matters here — a card with a big sequential read but no V-class is the wrong buy for video. The Samsung PRO Ultimate previously held this slot but is currently unbuyable; the Kingston Canvas Go! Plus (~$74.31, 200/90 MB/s, V30 + A2) is the closest in-stock alternative. [src3, src4] ### Best for 4K Video Production: SanDisk Extreme PRO 256GB (~$72.25) — [Check price](https://knowledgelib.io/go/sandisk-extreme-pro-microsd-256) For content creators who need maximum UHS-I performance, the Extreme PRO delivers 200 MB/s reads and 140 MB/s writes at essentially the same price as the standard Extreme ($72.25 vs $71.98, both $0.28/GB). Independent tests show it reaches close to its rated speeds consistently, making it suitable for high-bitrate 4K recording in cameras and drones that accept microSD. It includes RescuePRO Deluxe data recovery software. Stock is thin — it showed only a handful of units at last check, so buy the standard Extreme if it is gone. [src4, src3] ### Cheapest 256GB Card: SanDisk High Endurance 256GB (~$65.99) — [Check price](https://knowledgelib.io/go/sandisk-high-endurance-256) There is no longer a budget tier in this category. The sub-$30 256GB card has been wiped out by the NAND shortage, and at $65.99 ($0.26/GB) the SanDisk High Endurance is simply the cheapest 256GB card on the board. Be clear about what you are buying: it is an endurance-rated card at 100/40 MB/s, purpose-built for 24/7 dashcam and home-monitoring recording, not a fast general-purpose card. If you want cheap phone or Steam Deck storage, spend the extra $6 on the SanDisk Extreme instead — the write speed difference is more than 3x. [src1, src7] ### Best for Dashcams & Security Cameras: Samsung PRO Endurance 256GB (~$149.99) — [Check price](https://knowledgelib.io/go/samsung-pro-endurance-256) Designed specifically for always-on recording, the PRO Endurance uses enterprise-grade NAND flash that survives extreme heat and constant write cycles. The 256GB model is rated for up to 140,000 hours of continuous recording and withstands -25C to 85C. It is still the highest-endurance option, but it is now hard to justify on price: it climbed from ~$106 to $149.99 (+41%) between June and August 2026, making it $0.59/GB — more than double the SanDisk Extreme. **At today's prices the SanDisk MAX Endurance ($109.99, 120,000 hours) is the better endurance buy**, and the SanDisk High Endurance ($65.99) is the budget always-on option. [src7, src3, src10] ### Best Value Switch 2 Card: SanDisk microSD Express 256GB (~$74.79) — [Check price](https://knowledgelib.io/go/sandisk-microsd-express-256) The SanDisk 256GB Express remains both the fastest (880/650 MB/s, 210 MB/s sustained write) and the cheapest 256GB Express card at $74.79 ($0.29/GB), holding its lead over the Samsung P9 Express ($79.25). SanDisk also sells an officially licensed Switch 2 Express card (512GB, $149-200). Real-world Switch 2 game loading differences between Express cards are imperceptible, so this card wins on price-per-performance. Remember that it delivers Express speeds **only** in the Switch 2 — in a phone or camera it falls back to UHS-I. [src2, src5, src9] ### Best Samsung-Brand Switch 2 Card: Samsung P9 Express 256GB (~$79.25) — [Check price](https://knowledgelib.io/go/samsung-p9-express-256) Samsung's P9 Express delivers 800 MB/s reads and 600 MB/s writes at $79.25 — notably, it is the one Samsung microSD in this comparison that is still in stock on Amazon. Real-world Switch 2 game loading times are virtually identical to faster Express cards despite the lower rated speed. The P9 includes 6-proof protection (water, temperature, magnet, drop, wear, x-ray) and a 3-year warranty. Pick it if you specifically want Samsung's brand and warranty, but the SanDisk Express is still cheaper and faster. [src6, src8, src9] ### Best for Maximum Switch 2 Capacity: Lexar Play PRO 1TB (microSD Express) (~$349.99) — [Check price](https://knowledgelib.io/go/lexar-play-pro-express-1tb) With 900 MB/s reads and 600 MB/s writes via PCIe/NVMe, the Lexar Play PRO delivers top-tier microSD Express performance, and its 1TB capacity holds dozens of modern games. At $349.99 it works out to $0.34/GB — a premium over 256GB Express cards ($0.29/GB) but far less of one than it was in spring. It is backwards compatible with UHS-I devices. The price has been flat since June, which in this market counts as good news. [src2, src5, src9] ### Fastest UHS-I on Paper: Lexar Professional Silver Plus (~$134.99 for a 2-pack) — [Check price](https://knowledgelib.io/go/lexar-silver-plus-256) The Silver Plus is still the fastest UHS-I card tested (205/150 MB/s rated, and independent testing has it exceeding its write rating), with V30, A2 and a lifetime limited warranty. It lost the top spot on availability, not merit: the single 256GB card is out of stock, and the only live listing is a 2-pack at $134.99. That works out to $67.50 per card and $0.26/GB — the joint-cheapest $/GB in this comparison — so it is genuinely good value **if you need two cards**. If you only need one, buy the SanDisk Extreme. [src1, src3, src4] ### Samsung's UHS-I Line: Out of Stock (buy links point to Samsung's own store) The Samsung PRO Plus 256GB ($79.99 MSRP, 180/130 MB/s), EVO Select 256GB ($72.99 MSRP, 160/70 MB/s) and PRO Ultimate 256GB ($99.99 MSRP, 200/130 MB/s) are all excellent cards and all currently out of stock at both Amazon and Samsung's own US store. Their buy links here point to Samsung's official product pages so you can check restock and see the real MSRP. **Do not buy these from third-party Amazon marketplace sellers right now** — asking prices of $99.95 to $219.90 against $72.99-$99.99 MSRPs are pure scarcity mark-ups, and marketplace listings are also where counterfeit microSD cards concentrate. [src1, src10, src11] ## Head-to-Head Comparisons ### SanDisk Extreme vs SanDisk Extreme PRO The two are $0.27 apart at 256GB ($71.98 vs $72.25, both $0.28/GB), so price is not the deciding factor. The PRO is rated 200/140 MB/s against the Extreme's 190/130 MB/s — a real but small gap, and both carry U3, V30 and A2. The practical difference in August 2026 is stock: the Extreme is solidly in stock while the PRO has been showing only a handful of units. [src3, src4] **Pick SanDisk Extreme PRO if:** it is in stock and you record high-bitrate 4K, where the extra 10 MB/s of sustained write has a chance of mattering. **Pick SanDisk Extreme if:** you want the safe, always-available default — it is the better bet for a card you need today. ### SanDisk Extreme vs Lexar Professional Silver Plus 2-pack The Lexar is the faster card on paper (205/150 vs 190/130 MB/s) and, at $134.99 for two 256GB cards, the cheaper card per gigabyte ($0.26/GB vs $0.28/GB). But the single Silver Plus is out of stock, so buying it means buying two. [src1, src3, src4] **Pick the Lexar Silver Plus 2-pack if:** you genuinely need two cards — it is the best $/GB in this comparison and the fastest UHS-I card tested. **Pick SanDisk Extreme if:** you need one card. Paying $134.99 to get a single $67.50 card you will use is false economy. ### SanDisk microSD Express vs Samsung P9 Express The two flagship Express options for Switch 2. The SanDisk wins on both fronts: faster raw spec (880/650 MB/s vs 800/600 MB/s) AND cheaper ($74.79 vs $79.25) for the same 256GB capacity. Game loading time differences between the two on Switch 2 are imperceptible in independent benchmarks, so the spec gap is largely academic. [src2, src5, src6, src8] **Pick SanDisk microSD Express if:** you want the best value 256GB Express card — it is both cheaper and faster. **Pick Samsung P9 Express if:** you specifically prefer Samsung's brand and 3-year warranty and will pay ~$4.50 more for it. ### Samsung PRO Endurance vs SanDisk MAX Endurance Both are built for dashcams and 24/7 security cameras. Samsung PRO Endurance rates 140,000 hours at $149.99 ($0.59/GB); SanDisk MAX Endurance rates 120,000 hours at $109.99 ($0.43/GB). Samsung's 41% price jump since June flipped this matchup — the Samsung now costs 36% more for 17% more rated hours. [src7, src3, src10] **Pick SanDisk MAX Endurance if:** you are buying today. It is the better value on hours-per-dollar and is in stock. **Pick Samsung PRO Endurance if:** you need the absolute maximum endurance rating or the wider -25C to 85C temperature range for an extreme-climate install. ### SanDisk High Endurance vs SanDisk Extreme The cheapest-card question, now that the sub-$30 tier is gone. High Endurance is $65.99 and Extreme is $71.98 — only $6 apart. But High Endurance runs 100/40 MB/s and is tuned for continuous write-erase cycles, while the Extreme runs 190/130 MB/s with an A2 random-IOPS rating. [src1, src7] **Pick SanDisk High Endurance if:** the card goes in a dashcam, body cam or home security camera that records continuously. **Pick SanDisk Extreme if:** the card goes in a phone, Steam Deck, drone or action camera. For $6 more you get over 3x the write speed and A2 app performance. ## Decision Logic ### If user needs a card for a dashcam or security camera --> SanDisk MAX Endurance 256GB (~$109.99, 120,000 hours). It is now the best endurance value after the Samsung PRO Endurance climbed 41% to $149.99 for 140,000 hours. Standard cards will fail within months in always-on recording. For lower-budget dashcam use, SanDisk High Endurance (~$65.99); only choose the Samsung PRO Endurance if you need the maximum hour rating or the -25C to 85C range. [src7, src3, src10] ### If user needs a card for Nintendo Switch 2 --> SanDisk microSD Express 256GB (~$74.79) for best value — both the cheapest and the fastest 256GB Express card, undercutting the Samsung P9 Express (~$79.25). Real-world game loading differences between Express cards are negligible. For maximum storage, Lexar Play PRO 1TB (~$349.99, $0.34/GB). Do not buy an Express card for any other device: the Switch 2 is the only mainstream consumer product that supports the standard. [src2, src6, src8, src9] ### If user needs a card for a drone or action camera (GoPro, DJI, Insta360) --> SanDisk Extreme 256GB (~$71.98). V30-rated sustained 30 MB/s minimum write for 4K without dropped frames, plus A2. Temperature, water, shock and x-ray proof. If in stock, SanDisk Extreme PRO (~$72.25) is the same price with 200/140 MB/s. Kingston Canvas Go! Plus (~$74.31) is the third in-stock option. [src3, src4] ### If user wants the cheapest 256GB card --> SanDisk High Endurance 256GB (~$65.99, $0.26/GB) — but only for continuous-recording use. The sub-$30 256GB tier no longer exists; for general-purpose storage the cheapest sensible card is the SanDisk Extreme (~$71.98), because the High Endurance writes at 40 MB/s versus 130 MB/s. Do not treat these as interchangeable on price alone. [src1, src7, src10] ### If user wants the fastest UHS-I card available --> Lexar Professional Silver Plus (205/150 MB/s, often exceeds its write rating in testing, lifetime warranty). Caveat: the single 256GB card is out of stock and only a 2-pack is available at ~$134.99 ($67.50/card, $0.26/GB). If you need one card rather than two, SanDisk Extreme PRO (~$72.25, 200/140 MB/s) is the practical answer. [src1, src3, src4] ### If the user specifically wants a Samsung card --> Only the Samsung P9 Express 256GB (~$79.25) is actually buyable in August 2026. The EVO Select, PRO Plus and PRO Ultimate are out of stock at both Amazon and samsung.com — check samsung.com for restock rather than paying marketplace mark-ups of $99.95-$219.90 against $72.99-$99.99 MSRPs. [src1, src10, src11] ### If user needs 1TB or more storage --> For Switch 2: Lexar Play PRO 1TB Express (~$349.99). For UHS-I devices, 1TB cards from Lexar and SanDisk exist but have been hit hardest by the shortage — price them per GB against two 512GB cards before committing. Also confirm the device supports SDXC above 512GB (and SDUC above 2TB); many older phones and cameras do not. [src1, src3, src9] ### Default recommendation --> SanDisk Extreme 256GB (~$71.98) for general use; SanDisk microSD Express 256GB (~$74.79) for Switch 2 owners. SanDisk is currently the only brand with its full 256GB UHS-I range in stock, and the Extreme's U3 + V30 + A2 rating stack makes it the safe pick when the target device's requirements are unknown. [src1, src3, src10] ## Key Market Trends (Q3 2026) - **The shortage has turned from a price problem into a stock problem**: Samsung's entire 256GB UHS-I range — EVO Select, PRO Plus, PRO Ultimate — is out of stock at both Amazon and samsung.com as of 2026-08-05, and the Lexar Silver Plus 256GB single card is unavailable (only a 2-pack remains). SanDisk is currently the only brand with its full 256GB UHS-I line reliably in stock, which is why every general-purpose recommendation on this card now points to SanDisk. [src1, src10, src11] - **The sub-$30 256GB card is gone**: The Samsung EVO Select was the last one, at ~$25 in June; it is now $72.99 MSRP and unbuyable. The cheapest 256GB card in this comparison is the SanDisk High Endurance at $65.99, and it is endurance-tuned rather than fast. Effective floor for a good general-purpose 256GB card is now ~$72, or about $0.28/GB. [src1, src7] - **Median memory-card prices up 124% versus 2025, some SKUs up 261%**: Tom's Hardware's cross-format survey puts the median increase at 124%, driven by AI data-centre demand pulling NAND away from consumer products. Analysts do not expect meaningful relief until late 2027, when new fabs come online — a timeline that was pushed back again in July 2026. Waiting out the shortage is not a strategy. [src10, src11] - **Endurance pricing has inverted**: Samsung PRO Endurance 256GB jumped $106 → $149.99 (+41%) between June and August while SanDisk MAX Endurance held at $109.99. The Samsung now costs 36% more for 17% more rated hours, so the best-value endurance pick has flipped to SanDisk. [src7, src10] - **microSD Express is the calmest corner of the market**: SanDisk Express 256GB $74.79, Samsung P9 Express $79.25, Lexar Play PRO 1TB $349.99 — all roughly flat since June. Express cards were less exposed to the commodity NAND squeeze, and the P9 Express is the one Samsung microSD still in stock. [src6, src8, src9] - **Switch 2 still the only Express device**: The Nintendo Switch 2 remains the sole mainstream consumer device supporting microSD Express. Express cards fall back to UHS-I speeds (~100 MB/s) in all other devices, so they are still best understood as a Switch 2 accessory rather than a general upgrade. [src2, src5] - **UHS-I speeds have plateaued**: Top UHS-I cards reach 200-205 MB/s reads, at the practical ceiling of the UHS-I bus. Further gains require UHS-II (which needs a UHS-II host to deliver anything — in a UHS-I phone or camera a UHS-II card simply falls back) or Express. [src1, src4] - **Counterfeit risk rises with scarcity**: Stock-outs push buyers toward third-party marketplace sellers, which is exactly where counterfeit and re-badged cards concentrate. Buy from the brand's own Amazon storefront or the brand's own site, and capacity-test new cards with H2testw or F3 before trusting them with data. [src1, src11] ## Important Caveats - **Stock status changes faster than price right now.** Availability in the comparison table was checked on 2026-08-05. Three Samsung cards were unbuyable at both Amazon and samsung.com on that date; they may restock at MSRP at any time, so check before assuming they are gone. - Prices fluctuate frequently due to NAND flash supply constraints and retailer promotions; check current pricing before purchasing. - **Counterfeit microSD cards are a genuine, prevalent risk**, and scarcity makes it worse. Buy from the brand's own Amazon storefront (sold and shipped by Amazon or the brand) or the brand's own site — third-party marketplace sellers are where fakes concentrate. Capacity-test every new card with H2testw (Windows) or F3 (macOS/Linux) before trusting it with data. - **A high sequential read figure does not make a card suitable for video.** The V-class (V30/V60/V90) sets the guaranteed sustained write floor, and the A-class (A1/A2) sets random-IOPS performance for app and game storage. Match those classes to the device, not the headline MB/s. - **UHS-II cards need a UHS-II host.** In a phone, a Switch, a GoPro or any UHS-I slot they fall back to UHS-I speeds, so paying a UHS-II premium for a UHS-I device is wasted money. The same applies to microSD Express outside the Switch 2. - MicroSD Express cards are NOT backwards compatible as Express cards in older devices; they fall back to UHS-I speeds when used in non-Express slots. - Endurance-rated cards sacrifice raw speed for write-cycle durability; do not use them where fast sequential performance is needed. - Write speeds in the comparison table are manufacturer-rated maximums; real-world sustained speeds may be 10-30% lower depending on the device and file type. - This comparison uses 256GB as the reference capacity for consistent pricing, except the Lexar Silver Plus (sold only as a 2 x 256GB pack) and the Lexar Play PRO (1TB). $/GB is computed from the capacity actually priced in each row. Confirm your device supports SDXC (above 32GB) and, for 1TB+ cards, that it handles capacities above 512GB. - Warranties differ materially: Lexar Silver Plus is limited-lifetime, Samsung's UHS-I cards are 10-year (P9 Express is 3-year), and endurance cards are typically warranted by hours written rather than years. ## Related Units - [Best Portable External SSDs (2026)](/consumer-electronics/storage/external-ssds/2026) - [Best NAS Devices for Home (2026)](/consumer-electronics/storage/nas-devices-home/2026) - [Best External Hard Drives (2026)](/consumer-electronics/storage/external-hard-drives/2026) - [Best Dash Cams (2026)](/consumer-electronics/automotive/dash-cams/2026) - [Best Action Cameras (2026)](/consumer-electronics/cameras/action-cameras/2026)
