Seagate FireCuda 520N 1TB SSD Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random read performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

With our 4-threaded random 4K read test we couldn't get close to the official maximum of 800,000 IOPS with a best test result of 372,868 IOPS at QD32.

4K Random Read v QD Performance compared.

At queue depths 1 and 2, the drive sits in fourth and third place respectively but as the queue depth deepens it falls down the chart, never dropping out of the top 10.
