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 once again displays very strong results, both the 1TB and 2TB versions being identical.
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.
AS SSD provided consistent benchmarks to other software, and this was the only instance that we had seen a difference between the 1TB and 2TB drives, but only with respect to IOPS as we see here. The 1TB result is just a bit lower as shown here:
A bit unusual perhaps is the fact that the 860 QVO SATA 3 SSD identifies as the 860 Pro 4TB SSD in AS SSD and Anvil benchmarks. This could be due, in part, to the fact that this is early firmware and both share the same controller.
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.
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.
