Seagate Lightsaber Collection Special Edition FireCuda 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.

Seagate rates the 4K random read performance of the 2TB Lightsaber Collection Special Edition FireCuda as up to 1,000,000 IOPS. With our 4-threaded testing, we couldn't get close to this maximum figure. The best we saw was 413,723 IOPS at QD16, the performance does drop a little at the end of the test, with the drive producing a figure of 413,684 IOPS at QD32.

4K random read performance v QD compared.

At QD1 the Seagate Lightsaber Collection Special Edition FireCuda sits behind the standard 2TB FireCuda 530, but as the queue depth deepens the drives swap places and remain that way throughout the testing procedure.
