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 demonstrates great performance in sequential workloads but there may be just a bit of concern with smaller random workloads as we don’t usually see 4K results that low anymore.
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.
We find the Total Score of AS SSD to be a bit low and this is the result of the low 4k ransom data transfer speeds. On the other hand, the sequential performance is right up there, as are the file copy speeds.
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.
Anvil Storage utilities are confirming everything that we are seeing thus far; sequential performance that matches listed specifications with random performance on the low side of things.
AJA VIDEO SYSTEM DISK TEST
The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.
