Our Pick

SanDisk

SanDisk Extreme Portable 1TB
8.5/10

The non-Pro Extreme is the lower-cost sibling — same 1050 MB/s rated read and IP55 rugged body, but writes top out well below Extreme Pro on sustained workloads. A solid buy when the write-speed gap doesn't matter (game consoles, file transfer, backup) but the rugged rating does.

Seagate

Seagate One Touch SSD 2TB
7.8/10

The 2TB One Touch is the sweet spot of Seagate's budget portable line — large enough die stack that the sustained-write dropoff after SLC exhaustion is significantly longer than on the 1TB.
