Our Pick

Samsung

Samsung T9 2TB

9.6/10

The 2TB T9 doubles the write endurance of the 1TB while keeping the full 20Gbps Gen 2x2 link. The right size for working 6K Blackmagic RAW footage in the field — sustained 2 GB/s means editing directly off the drive is indistinguishable from internal storage.
