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.
The drives we tested were tightly grouped in the SANDRA physical disk benchmark. Although the SanDisk Extreme Pro drives didn't lead, only a few MB/s separate all of the contenders here.
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 excellent performance from the SanDisk Extreme Pro drives in the ATTO disk benchmark. Performance was good across the board, but small block sizes in particular were a strong point.
