4K Sustained Random Read
Samsung quotes a maximum 4K random read rate of 500,000 IOPS at a queue depth of 32 and with 4 threads, a number we could confirm with our test; the tested drive producing 501,600 IOPS.
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 all queue depths the Samsung 970 Pro 1TB drive reigns supreme when it comes to 4K random reads.
