We used CrystalDiskMark 8‘s custom settings to test the 4K random write 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.
As with random reads, the G560 is rated up to 1,400,000 IOPS for random writes. Once again we couldn't get close to that figure with our 4-threaded test with a best peak result of 442,926 IOPS at QD16.
4K Random Write v QD compared.
The drive sits in the bottom half of the results table for all of the tested queue depths, the highest position it gains is from the QD1 test. For the rest of the tested queue depths, only the Phison PS5031-E31T has a slower performance than it does.
