Plextor M6M 256GB mSATA 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 Plextor M6M 256GB drive offered very competitive read performance, but trailed the other drives in write bandwidth.
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 Plextor M6M 256GB drive performed well in the ATTO read test, with transfer sizes up to and including 32KB, but trailed off a bit with larger transfers. Writes, however, generally trailed the competition.
