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.
In examining the Crystal DiskMark result you might notice that the low 4K read and write performance is a bit low. We actually had to conduct the test twice as it wouldn’t complete the first time. The device seems to have difficulty testing low random performance.
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.
With AS SSD, we found that it wouldn’t complete at allonce it started low random testing. Sequential completed without difficulty, however.
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 Utilities completed without difficulty, displaying the listed specs of 1GB/s read and write. We can see once again that the low random performance is much lower than is typical in today’s SSD devices.
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.
Last test for the day, the AJA benchmark was quick and easy. Although our report is just a bit dated, we wanted to give JMicron a big kudos for giving us an early look at this adapter.
You can find these types of solutions avvailable on Amazon now, and we would guess any issues might have been ironed out. Check here for similar USB 3.1 (Gen 2) to NVVMe storage devices.
