Officially the drive is rated for random 4K writes up to 260,000 IOPS. As you can see from our results we couldn't get anywhere close to this figure with our 4-threaded tests, the best result we got was 56,898 IOPS at a queue depth of 32. As with the random reads, we tested the drive at a queue depth of 32 using eight threads and got a figure of 236,662 IOPS, a lot closer to the official figure.
4K Random Write v QD Performance
As with the random read testing, the P300 doesn't handle our 4K random write tests, sitting at the bottom of all but one of our result charts.
