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).

 

This graph shows the Maximum Latency values for each combination of Read/Write Mix and IO Size.

 

 

This graph shows the Average Latency values for each combination of Read/Write Mix and IO Size.  These are excellent results. 


SNIA Latency Test – Product Comparison

For interest we present a comparison of the 4K 65% Reads 35% Writes latency results in comparison with those of the other Enterprise SSDs I have tested –

An outstanding result.

 

An outstanding result, which bodes well for the Intel DC P4510’s Quality of Service, which we look at more closely on the next page.

Now let’s head to the next page, to look at the results for the Myce/OakGate 4K Read and Write Latency Tests……
