Intel DC P4510 8TB NVMe Enterprise SSD Review

SNIA Latency Test

The Latency Test measures average and maximum response times
using random IOs at specified Block Sizes and Read/Write mixes, taken under
steady state conditions.  The test runs at a Queue Depth of 1 (1 outstanding
IO), thus the results give the baseline response time for a single IO request.

The test also reports maximum latency values, which can be
helpful to see if there might be processes within the drive that may cause max
Latency values to become larger.

Here are the results –

You can see here that Steady State was achieved in Round 1
through Round 5 (the ‘Measurement Window’). Note that the 4K Write line is used
to determine the achievement of steady state.

These are the Average and Maximum Latency Values observed in
each round of the Measurement Window (measured in Milliseconds).
