Toshiba PX04SMB160 SAS 1600GB Enterprise SSD Review – The SAS Awakens

Myce/OakGate Reads and Writes Tests

The tests are designed to show the Random and Sequential,
Read and Write, performance metrics for different combinations of Queue Depth
and IO size.

Here are the results for each combination of Power Mode and
Single/Dual Port operation –

Please pause here for a moment to note the incredible random
4K Queue Depth 1 read speed of 84.56 MB/s.  This is the fasted random 4K QD 1
read speed I have ever seen.

Comparison of Selected 4K Random Reads Results for Each
Combination of Power Mode and Single/Dual Port operation

For interest here are the results for 4K Random Reads at
Queue Depth 32 for each combination –

          Power Efficiency Mode and Single Port                            799.11
MB/s

          Power Efficiency Mode and Dual Port                               1,415.17
MB/s

          Maximum Performance Mode and Single Port                  803.84
MB/s

          Maximum Performance Mode and Dual Port                     1,419.4
MB/s

We can see that the two power modes have similar results but
dual port delivers significantly improved 4K random read performance.
