Our Pick

Samsung

Samsung T7 500GB
9.0/10

The base T7 is the SSD most people should buy — a pocket-sized aluminum slab that delivers the full 10Gbps USB experience without a rugged premium. Its understated metal body doubles as a heatsink, keeping sustained writes pegged at 1000 MB/s even on long 50GB+ transfers.

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.
