Samsung 970 PRO 1TB SSD Review

128KB Sequential Read / Write

In our 128KB sequential read/write tests, our results confirm the official figures of 3,500MB/s, with the drive producing 3,566MB/s while writes came in at 2,753MB/s confirming the official 2,700MB/s

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 at a queue depth of 32 – although in the desktop environment you'll seldom, if ever, see a queue depth that high.

128KB Sequential Read Queue Depth results

At a queue depth of 1, the 970 PRO falls someway short of the 960 PRO, but at a queue depth of 2 and beyond it's the 970 PRO that reigns supreme.

128KB Sequential Write Queue Depth results

At a queue depth of one, the 970 PRO sits just behind the 970 EVO – but at a queue depth of 2 and beyond it's the WD Black NVMe that has the edge.
