SanDisk Extreme Go USB Flash Drive, Up to 400MB/s Read, 64GB–256GB

Rated 400MB/s read and 240MB/s write at 256GB, but the 64GB version is quoted at only 100MB/s write - the capacity chosen changes what this drive is fit for, not just how much it holds.

Metal Type-A body, 128-bit AES password protection through SanDisk's software, lifetime limited warranty. Where writes matter more than price, the SanDisk Extreme PRO USB 3.1 Solid State Flash Drive is rated higher again.
