Our take on the SanDisk Extreme 512GB microSD (245MB/s)
The SanDisk Extreme 512GB microSD is a V30 card with read speeds up to 245MB/s and write speeds up to 170MB/s. It costs a tracked $139.99, the top of its $129.99 to $139.99 range since August 26, 2026, so wait for a dip.
SanDisk lists 5K video support, handheld console and action camera compatibility, and a Memory Zone app for backups. For a streamer, the write speed matters most for recording, and 170MB/s is well above basic cards. The listing also mentions capacities up to 2TB across the line. Retailer ratings average 4.7 over 1,336 reviews. It is a lot of card for a camera backup.
- Up to 170MB/s write speed
