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

Myce/OakGate 4K Mixed Reads/Writes Tests

This test is designed to show the performance metrics for
different combinations of Queue Depth and Read/Write mix (the % of Reads and
the % of Writes making up the IO traffic) 

4K Mixed R/W Test

With Dual Port operation we see an increase in Total IOPS
compared to Single Port, at the lower levels of Write %, dropping away towards
no difference as the Write % increases.

In Maximum Performance Mode we again see a greater IOPS
level for dual port operation compared to single port operation, towards the low
Write %, with a drop off in the difference towards the higher levels of Write
%.  Indeed the total IOPS level falls slightly below that of single port
operation as the Write % increases.
