Host requirementsRequired interface and operating conditions. Using a faster host port does not upgrade the enclosure bridge. Formatting and file-system support are separate. | Thunderbolt 4, Thunderbolt 3 or USB4 Type-C ports are required for optimal use; USB 3.2 Gen 2 and older hosts run at lower rates.

Explicit compatibility limitsImportant exclusions and capacity or revision conditions. Use the exact drive and enclosure revision.

| Questions to check before buying | Satechi's own page gives two size lists, so 2230 support needs confirmation. The box list names only the enclosure while the FAQ refers to an included USB4 cable, thermal pad and case; the exact US box contents are unresolved. |
