This blog concludes the a series which present test results of block size and outstanding IO request size on SSD IO bandwidth.  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: OCZ Vertex 3 120 GB SATA based SSD


Figure 1: IO Bandwidth for  OCZ Vertex 3  Drive: a) random read b) sequential read


Figure 2: IO Bandwidth for  OCZ Vertex 3   Drive: a) random write b) sequential write

Figures 1 and 2 shows the results for the  OCZ Vertex 3  SSD. Like previous results, the request size dominates the performance.
