Plextor M6e Black Edition PCI Express SSD Review, M.2 In The Slot

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 Plextor M6e and M6e Black Edition performed right on top of each other in the SiSoft SANDRA physical disk benchmark as well. Reads were significantly faster than the SATA drives, but writes were only marginally higher.
 
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.

The ATTO Disk Benchmark tells essentially the same story as SANDRA. The M6e and M6e Black Edition performed similarly, and write performance was only slightly better than the SATA drives. Read performance was good too, though with smaller block sizes, the additional bandwidth afforded by the PCIe-based M6e Black Edition and M6e doesn't help much at all.
