Samsung 970 EVO 2TB SSD Review

128KB Sequential Read / Write.

As with the ATTO benchmark, our 128KB Sequential test saw a read result a little shy of the official 3,500MB/s figure – at 3,402MB/s – but our write figure of 2,515MB/s confirms Samsung's official 2,500MB/s figure.

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 low queue depths the 970 EVO's best sequential read performance comes at a queue depth of 2, with a figure of 2,594MB/s.

When it comes to sequential writes, the 970 EVO's performance is much more consistent through the lower queue depths than it is when reading.
