Effect of Block Sizes and Outstanding IO Requests on SSD performance - Intel X25-V
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

Test SSD: Intel X25-V SATA based SSD
Figure 1: IO Bandwidth for Intel X25-V Drive: a) random read b) sequential read
Figure 2: IO Bandwidth for Intel X25-V Drive: a) random write b) sequential write
Figures 1 and 2 shows the results for the Intel X25-V SSD. For both random read and random write requests, the request size determines the maximal performance.
The interesting result for this drive is that the maximum write performance is achieved even for very small request sizes for both random and sequential write requests.
Come back next week for results and observations on another SSD.
