SANDRA and ATTO Disk Benchmark

Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on unformatted drives and read and write performance metrics are detailed below.

SiSoft SANDRA 2014
Synthetic HDD Benchmarking


According to SiSoft SANDRA's physical disk benchmark, the new OCZ Vertex 460 offers very competitive read speeds and writes are among the best as well. Only a few MB/s separate the top performers in this test.

ATTO Disk Benchmark

ATTO is another "quick and dirty" type of 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 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.

The Samsung 840 EVO put up some of the better scores in the ATTO Disk Benchmark, but generally speaking, all of the drives are tightly grouped here--for the most part. The Extreme II's performance bounced around a bit depending on the transfer size, though it was clearly the fastest of the bunch with small transfers and in read performance overall.
