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.
Listed speeds for the Plextor M6S are 520MB/s read and 440MB/s write and, as we can see, ATTO seems to be right on the money. Keep in mind though that the transfer of highly compressible data is easier than incompressible data and ATTO matches manufacturer specs 99.99% of the time.
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.
High sequential performance dropped a bit with AS SSD but the Total Score is above 1000 points which demonstrates the making of an upper tier SSD. We also get our first look at IOPS with 88217 IOPS read and 75319IOPS write, just below listed specs.
The Plextor M6S SSD also provided decent AS SSD Copy benchmark results with transfer speeds of ISO and Game sample files reaching SATA 3.
Anvil Storage Utilities (ASU) are 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.
Throughput and IOPS are a bit lower than expected in ASU, however, a Total Score above 4K (4031) validates that this is a strong SSD. Let’s see if we can reach the listed IOPS of 90,000 read and 80,000 write.
