4K Sustained Random Write.

As with our 4K random read test, the fastest random write figure fell well short of the official 480,000 IOPS – at 316,863 IOPS – however this still makes the 970 EVO the third fastest drive we've seen to date for 4K random write performance.

Most desktop operations happen in the 1 – 4 queue depth range, so we've broken out the test results to see how the drive performs at these queue depths in comparison with other drives, as well as a queue depth of 32 – although in the desktop environment you'll seldom if ever see a queue depth that high.

At a queue depths 1 and 2, the 970 EVO is the fastest consumer drive we've seen producing 179.417 IOPS and 314,730 IOPS respectively.
