microSD Express 256GB U3 V30 A1
P-SDU256P31880EXP-GE · ASIN B0F8PDR71RThis 256GB microSD Express card meets the Switch 2 format requirement. PNY rates it up to 890MB/s read and 750MB/s write in a capable host, but these are peak claims and the listing does not establish game-loading advantage over SanDisk. In an ordinary UHS-I/II device it falls back to that host's speed. Review feedback for the selected 256GB option mentions that it works with Switch 2. The checked offer was sold and shipped by Amazon.ca, with a ten-unit stock warning and a 5 October delivery estimate to Balzac T4B 2T3. PNY lists a limited lifetime warranty and an available trial recovery-software offer, subject to terms.
