ATTO Disk Benchmark

The ATTO disk benchmark tests the drives read and write speeds using gradually larger size files. For these tests, the ATTO program was set to run from its smallest to largest value (.5KB to 8192KB) and the total length was set to 256MB. The test program then spits out an extrapolated performance figure in megabytes per second.

As you can see, the performance curves of this RAID array are impressive but on the all important small end of the spectrum this raid array is nowhere close to being twice as fast as one Seagate drive. With that being said the boost in performance is noticeable and it does quickly ramp up to a performance level well beyond what any single hard drive is capable of – regardless of spindle speed.
