Plextor M9Pe M.2 NVMe SSD Review (1TB)


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

ATTO shows that the M9Pe is capable of over 3.1GB/s read and nearly 2.1GB/s write speeds. While just shy of the 3.2GB/s spec that it is rated it, these numbers are still very fast.


Crystal Disk Benchmark is used to measure read and write performance through a sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.


Crystal Disk Mark shows us very similar results. Looking at the sequential read and write speeds we can see that the Plextor M9Pe is capable of almost 3.2GB/s and 2.1GB/s, respectively. 4K QD1 performance is very good here as well. Reads average 65MB/s and writes averaging 200MB/s.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD, the Plextor M9Pe achieved a very high overall score of 3218 points. Sequential performance comes in at 2.7GB/s for read and almost 2GB/s for write. 4K QD 1 performance is a little slower than it showed in CDM, which is normal. Additionally, we can see that during the AS SSD Copy test that the M9Pe did very well and averaged over 2GB/s during the ISO portion!


Anvil’s Storage Utilities (ASU) is the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


Anvil Storage Utilities once again confirms all the performance numbers we have been seeing and overall, the Plextor M9Pe achieved an overall score of 13,463 points.
