Micron M500DC Enterprise Class SSD Review
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.
According to SiSoft SANDRA's physical disk benchmark, the new Micron M500DC series drives offered competitive read and write speeds, and trailed only the Intel drives.
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 Micron M500DC series drives offered some of the best performance here, with the smaller block sizes. Once they hit the 32K mark though, performance landed about in the middle of the pack.
