Plextor M6V SSD (256GB) Review – A Solid Value Entrant


ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.

Atto - Plextor M6V

Our first benchmark is rather impressive, especially considering that the drive is pretty well used before we even got our hands on it. It reached up to 561 MB/s read and 355 MB/s write.


Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.

Crystal Disk Mark - Plextor M6V

The random data test through Crystal Disk Mark is also impressive, considering what we know. At 534 MB/s read and 357 MB/s write, the drive is performing excessively well.


AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. Transfer speeds (MB/s) are seen in the left picture below and IOPS (Input/Output Operations Per Second) are on the right.

Rather interesting is the drive’s ability to keep up with our testing. The drive just came in a little light in terms of performance, but still provides decent performance.

Another interesting feature of the AS SSD Benchmark is that it also can test duration and speeds of copying various files, this is an important test for our digital media professionals who require top transfer speeds.

AS SSD 3 - Plextor M6V

Transferring an ISO and Game shows fairly adequate performance at 487 MB/s and 380 MB/s, but transferring a Program came in much lower than we anticipated.


Anvil Storage Utilities is essentially an all-in-one tool for all of your SSD benchmarking needs. Anvil can be used for basic consumer testing, as well as endurance testing and threaded I/O read, write and mixed tests. It displays data regarding the SSD, and even about your system

ASU - Plextor M6V

The sequential performance of the Plextor M6V again shows up nearly spot on to where we expected the results to land, but just a bit shy. These are still decent results, and the difference between where they land and what is expected would not be remotely noticeable upon usage.
