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 Disk Mark shows us again read and write speeds that are in line with the 560MB/s read and 500MB/s write spec. 4K speeds look very good as well with reads reaching 34MB/s and writes reaching 151MB/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.
Looking at the performance in AS SSD we can see that it achieved an overall score of 904 points. As normal read and write speeds are a bit slower than in the other benchmarks with reads coming in at 526MB/s and writes reaching 478MB/s. AS SSD also gives us a look at IOPS performance. For reads it was able to deliver performance over its 75K rating, reaching 78K IOPS, however, during writes the IOPS are half of specification, reaching only 25K.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s 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.
Finally, Anvil shows off an overall score of 4155 points. Read and write performance is in line with AS SSD’s results, however, in terms of IOPS we see an improvement in writes. The Premier SP550 reached just shy of 70K write IOPS, which is much better than AS SSD revealed.
