SanDisk's 256GB Ultra is a straightforward capacity step up from the 128GB Ultra already in this lineup, at the same 195MB/s read speed and same 10-year warranty. It's the card to buy when 128GB isn't enough headroom for 4K footage or a large app library but you don't need the Extreme PRO's faster write speeds — at $59.99 it's $33 cheaper than the 256GB Extreme PRO for buyers who are card-capacity-constrained rather than write-speed-constrained (casual photography, Android storage expansion, Nintendo Switch game libraries). With over 1,600 reviews at 4.6 stars, it carries the same trust profile as SanDisk's other Ultra-line cards already in this catalog. If you're shooting burst photography or 4K video and need sustained write performance, spend the extra $33 on the Extreme PRO instead.
