Performance in Intel IOMeter Sequential Read and Write Patterns

In the tables below, you can find the results obtained in Sequential Read and Write patterns where we tested the ability of our disk array to work with ordered requests with linearly growing address. For a simpler analysis the best results are highlighted in blue and the worst – in red color. Moreover, we also summed the results up in four graphs below.

Let’s start with Sequential Reading:

In RAID 0 configuration the array performed slower with ITE IT8212F controller, which you can clearly see for all data blocks. VIA VT6410 controller allows disk drive array show its real best when processing small data blocks. Both Promise controllers prove highly efficient for data blocks bigger than 8KB, and let our RAID array reach its performance maximum easily.

RAID 1 array shows that VIA VT6410 controller is in a more advantageous situation than its rivals. Despite the fact that the maximum read speed is almost the same by all controllers, the array performs the fastest of all when processing small data blocks exactly with VIA VT6410 controller. The slowest one here is ITE IT8212F.
