Sabrent quote a maximum 4K random read figure for the drive of 650,000 IOPS. The best we saw from the drive using our own 4-threaded tests was 409,738 IOPS (1,678.29 MB/s) at a QD of 32.

4K Random Read v QD Performance compared.

Sabrent’s Rocket 4 Plus sits in third place in our random read charts behind the WD Black SN850 and Samsung SSD980 PRO at a QD of 1 while it tops the chart at QD2. QD4 sees it sitting behind the WD drive again while at QD32 its sits behind both the WD drive and the 2TB version of the Rocket 4 Plus.
