Sabrent Rocket Q4 Review

The Sabrent Rocket Q4 uses QLC NAND to reach some of the largest available capacities in the consumer NVMe category, up to 8TB, targeting buyers who prioritize raw storage space over top-tier write performance.

At up to 4,700 MB/s read and a notably lower 2,000 MB/s write, this drive's QLC design trades sustained write speed for a substantially lower cost per terabyte at high capacities, appropriate for archival and read-heavy storage rather than heavy write workloads. Against the Sabrent Rocket 4 Plus, covered elsewhere on this site, that TLC-based drive delivers far stronger sustained write performance at a higher price per terabyte. Against the Corsair MP600 Core XT, also covered elsewhere on this site, both use QLC NAND to maximize capacity-per-dollar.

Against the Sabrent Rocket 4 Plus, covered elsewhere on this site, that TLC-based drive delivers far stronger sustained write performance at a higher price per terabyte. Against the Corsair MP600 Core XT, also covered elsewhere on this site, both use QLC NAND to maximize capacity-per-dollar.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Buyers who need maximum storage capacity for archival, media libraries, or read-heavy workloads at the lowest cost per terabyte. QLC NAND makes this drive's high capacities genuinely affordable.

Not for

Not for buyers running sustained heavy write workloads like large video exports. The Sabrent Rocket 4 Plus, covered elsewhere on this site, handles that scenario far better.
