Crystal Disk Benchmark is used to measure read and write performance through 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 DiskMark results of 564MB/s read and 536MB/s write are excellent although we might like to see the low 4k random write bump up just a bit.
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.
Once again, very strong results from AS SSD considering this is a SATA 3 SSD. We also get a first glimpse a 4K IOPS, which are right around listed specs.
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.
ASU might be a bit lower in throughput but did push the IOPS up a bit, which is a tad unusual as this benchmark usually beats up on IOPS scores.
Similar to ATTO, Quickbench is another utility that throws different data sample sizes at the SSD, measuring the data transfer speed. Typically, our results with Quickbench are much lower than we might see with ATTO.
