Sabrent Rocket 4 Plus 1TB SSD Review

The official 4K random write rating for the Rocket 4 Plus is up to 700,000 IOPS. As you can see from our 4-threaded test results we couldn't get close to that figure, the best we saw was 324,013 IOPS at QD32. We did a quick test at QD32 using 8 threads and saw the IOPS figure rise to 490,121 IOPS.
