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.

Synthetic HDD Benchmarking

The OCZ ARC 100 240GB drive offered competitive read performance here, but writes trailed all of the other drives, save for the Crucial MX100.
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.




We saw some weirdness in the ATTO Disk Benchmark with the OCZ ARC 100 240GB drive. Overall, performance was competitive, but with 64K and 2MB transfers, performance dipped somewhat in the read test. The write test showed a similar anomaly, but only with 64K transfers.
