Plextor M6e 256GB 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.

ATTO – Overlapped I/0:


Benchmark Results: ATTO showed the Plextor M6e 256GB M.2 SSD maxing out at 727 MB/s read and 578MB/s in the standard overlapped I/O benchmark. The drive is rated at 770MB/s read and 580MB/s write, so our read speeds are a bit lower than we hoped for in this benchmark.

AS-SSD (1.7.4739.38088) Benchmark:

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from all three of them.



Benchmark Results: AS SSD showed the Plextor M6e 256GB M.2 SSD topping out at 673.21 MB/s read and 545.08 MB/s write in the sequential benchmark. The copy benchmark showed the speed topping out at 386.52 in the game test, which is pretty damn good for a single SSD!


Benchmark Results: Performance on the Plextor M6e 256GB M.2 SSD appeared to be fairly consistent when it came to compressible data as read performance was just below 700MB/s over the entirety of the drive and the write scores were right around 540MB/s.
