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 Samsung SSD 850 EVO also performed right in-line with the higher-end Samsung SSD 850 PRO in the SANDRA Physical Disk benchmark.

ATTO Disk Benchmark
More Information Here: http://bit.ly/btuV6w

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 by the Samsung SSD 850 EVO in ATTO, especially with smaller block sizes. With transfers in the .5K to 32K mark, the Samsung SSD 850 EVO and PRO can't be touched.
