This blog continues the a series which present test results of extensive testing performed at Velobit to investigate SSD IO bandwidth when SSDs are operated in a simulated enterprise environment.  The test set up and procedure is documented in the first blog post of this series which can be found by clicking here.

Test SSD: Intel 320 SATA based SSD


Figure 1: IO Bandwidth for Intel 320 Drive: a) random read b) sequential read


Figure 2: IO Bandwidth for Intel 320  Drive: a) random write b) sequential write

Figures 1 and 2 shows the results for the Intel 320 SSD. Like previous results, the request size dominates the performance.  For all test cases,  the SSD reaches the peak performance when the queue length is  8.


Come back next week for results and observations on another SSD.
