Seagate quote 4K random read performance of the 1TB drive as up to 620.000 IOPS. With our 4-threaded 4K random read tests we couldn’t get close to that figure, the best we saw was 372,352 IOPS. We did a quick test using 8-threads at a QD of 32 and got a read score of 508,651 IOPS, a good deal closer to the official maximum figure.
4K Random Read v QD Performance Compared
The 4K random read performance of the FireCuda 510 compared to other drives using the same controller/NAND combination at QD’s 1 & 2 is very good, leading the way in fact. At QD4 the performance compared to the others starts to fall away before coming back strongly at QD32.
