Netac

Netac ZX1 1TB

7.5/10

A budget Gen 2x2 portable from Netac — aggressive price vs the brand-name tier. The 1800 MB/s write rating is real but drops further on sustained workloads past the SLC cache. A valid budget pick for game-library overflow where peak sustained write doesn't matter.

Our Pick

Sabrent

Sabrent Rocket XTRM-Q 4TB

8.7/10

A 4TB Thunderbolt 3 portable SSD is genuinely rare — most vendors cap at 2TB. The 4TB XTRM-Q is the enthusiast-choice for working 8K RED RAW footage in the field. Price is high but for revenue-grade video work that needs the speed, nothing else at this capacity competes.
