Plextor M6e Black Edition M.2 PCIe SSD Review


ATTO & AS-SSD Benchmarks

ATTO v2.47

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB.

Plextor M6e Black Edition 256GB:


Benchmark Results: ATTO showed the Plextor M6e 256GB M.2 SSD maxing out at 727 MB/s read and 586MB/s write in the standard overlapped I/O benchmark. The new Plextor M6e Black Edition drive topped out at 720 MB/s read and 579MB/s, which is actually slightly slower than the original drive. Keep in mind that the original drive is running Firmware v1.0.4 versus v1.0.5 on the Black Edition drive. There is also a difference in the PCB design as well. Both drives are rated at 770MB/s read and 580MB/s write, so our read speeds are a bit lower than we were looking for in this benchmark.
