Seagate FireCuda 520N 1TB SSD Review

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

128KB Sequential Read / Write.

Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.

We could confirm the official Sequential performance ratings of 4,800MB/s and 4,700MB/s for reads and writes respectively with this test, with results of 4,820MB/s for reads with writes at 4,823MB/s.

128KB Sequential Read v QD compared.

At QD1, the 1TB FireCuda 520N sits at the bottom of the results chart, but as the queue depth deepens the drive moves up the chart but it slips back down at QD32.

128KB Sequential Write v QD compared.

When it comes to Sequential writes, the FireCuda 520N sits in third place on our results chart at QD1, but the drive slips down as the queue depth deepens but it never drops out of the top ten.
