■ The catch — co-equal billing, always
It is not the fastest card here. The Lexar Silver Plus is rated 205/150 MB/s and the Extreme PRO 200/140, against this card's 190/130. You are buying availability, not the top of the spec sheet — the single Silver Plus is out of stock and the Extreme PRO has been down to a handful of units.

Traps — this verdict avoids
Why the SanDisk Extreme 256GB is right for you
It avoids every trap below — and for anyone, under $80, it is the pick because it delivers:
Counterfeit cards
Fakes concentrate on third-party marketplace listings, and the stock-outs are pushing buyers straight at them — sellers are asking $99.95 to $219.90 for Samsung cards whose MSRPs are $72.99-$99.99. Buy from the brand's own storefront or the brand's own site, and capacity-test every new card with H2testw or F3 before trusting it with data.
Express is a Switch 2 feature
MicroSD Express cards fall back to UHS-I at around 100 MB/s in anything except a Nintendo Switch 2 — still the only mainstream consumer device that supports the standard. Buying one for a phone, a GoPro or a laptop reader is money burned.
The cheapest card is a slow card
The cheapest 256GB card on the board is endurance-tuned at 100/40 MB/s — about a third of the SanDisk Extreme's 130 MB/s write, and with no A2 random-IOPS rating. The sub-$30 256GB tier no longer exists; $6 more buys a genuinely faster card.
