Samsung

Samsung T7 1TB

9.2/10

The 1TB T7 is the value sweet spot of Samsung's portable line — big enough for a working photo/video library, fast enough for direct 4K ProRes editing, and still small enough to live in a jacket pocket. The aluminum chassis keeps the drive cool under sustained workloads that throttle lesser plastic-bodied drives.
