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.
Right off the bat, we can see that the M8V is quite the capable SSD. Here, in ATTO, it delivers speeds of up to 565MB/s read and 511MB/s write. Looking at how it ramps up to speed, we can see that the M8V is even able to outpace the Intel 760P PCIe NVMe SSD up to the 4K file size!
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.
Similar to what we saw in ATTO, the M8V is able to deliver over 560MB/s read and 510MB/s write speeds in Crystal Disk Mark. Taking a look at the M8V’s 4K QD1 performance, it looks to be decent, but nothing really noteworthy with reads at almost 39MB/s and writes at over 132MB/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 M8V achieved an overall score of 1019 points. Sequential performance comes in at 531MB/s for read and 484MB/s for write. 4K QD 1 performance is about the same as before, only 4K read comes in at almost 42MB/s while 4K write comes in at 118MB/s. Additionally, we can see that during the AS SSD Copy test that the M8V did fairly well with ISO and Game speeds at over 450MB/s.
ANVIL STORAGE UTILITIES PROFESSIONAL
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 M8V achieved an overall score of 4,704 points.
