ATTO is one of the oldest hard drive benchmarks that is still used
today. ATTO measures transfers across a specific volume length. It
measures raw transfer rates for both reads and writes and places the
data into graphs that you can easily interpret. The test was run with
the default runs of 0.5kb through 8192kb transfer sizes with the total
length being 256mb.
Single Drive AHCI Performance:
Two Drive RAID 0 Performance:
Benchmark Results: The Kingston SSDNow V Series 40GB Boot Drive was able to reach 200MBps on the read test, which is a solid score but with two drives in RAID 0 we saw the performance jump up to 371MB/s. The write performancenearly doubled as we went from 46MB/s to 89MB/s! Something strange was happening with file sizes larger than 1MB with RAID though as read performance significantly dropped.
