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 Convergence was achieved
at the end of Round 5.
These are the Average Latency Values observed in the
Here is a 3D graph showing, at a glance, the Maximum Latency
values for each combination of Read/Write Mix and IO Size.
Here is a 3D graph showing, at a glance, the Average Latency
values for each combination of Read/Write Mix and IO Size. These are awesome
For interest we present a comparison of the 4K 65% Reads 35%
Writes latency results in comparison with those of the other Enterprise SSDs we
have tested –
Please note that the performance of the Intel P3700 has
caused us to change these comparison charts to report in Microseconds (as
opposed to Milliseconds). We have also taken the opportunity to change the
results to the average of those seen in the Measurement window (i.e. as
presented in the graphs).
Now let’s head to the next page, to look at the results
for the Myce/OakGate 4K Read and Write Latency Tests……
