Seagate FireCuda 520 1TB SSD Review

Seagate quote 4K random read performance as up to 760,000 IOPS. Using our standard 4-threaded 4K random read test we couldn’t get close to that number, with the drive producing a figure of 384,190 IOPS at a QD of 32. We did test the drive again at QD32 but with double the number of threads and got a figure of 555,330 IOPS, still well shy of the official maximum.

4K Random Read v QD Performance Comparison

At lower queue depths the FireCuda 520 loses ground on most of its competitors. However, at a QD of 32, it trails only Patriot's Viper VP4100.
