ATTO Disk Benchmark V.2.46
ATTO Disk Benchmark is the quickest and simplest method to determine transfer speeds and utilizes the same test methodology as manufacturers in arriving at performance results. It simply measures raw sequential transfer speeds for both read and write access at various transfer sizes, producing a very easily understood result.
Here we can see the controller pretty much maxing out the available read speed of the drives. The read speeds are absolutely superb, and the writes do hang a bit low, as the RAID 5 writing penalty and the MLC drives we are using do show their weakness.
Again in this round of testing we will do a test of “forced caching” in order to highlight the speed of the 1GB off DDR3 on this controller.
