ATTO Disk Benchmark
ATTO is another synthetic disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 10 over a total max volume size of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than IO response time, access latency etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.
In our ATTO testing, the Intel SSD 910 offers up an admirable performance curve, in line for the most part with its datasheet specifications for raw read/write bandwidth. The SSD 910 actually out-performs all other solutions here with the exception of OCZ's Z-Drive R4 product, which is able to push close to the 3GB/sec mark for reads and well in excess of 2.5GB/sec for writes in this test. We think of ATTO as sort of a best-case test condition for most storage solutions around here; so think of these plots as pretty much the best foot forward for each of the products we tested.
