Kingston SSDNow UV400 SSD Review (480GB)

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

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 Crystal Disk Mark the Kingston SSDNow UV400 achieved 540MB/s read and 531MB/s write. 4K random performance was decent with 33MB/s read and 136MB/s write.

AS SSD BENCHMARK VER 1.8

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.

When testing in AS SSD the UV400 reached an overall score of 1077 points. Sequential speeds are a bit less than the other benches, but still both read and write speeds are over 500MB/s. 4K read matched crystal disk mark at 33MB/s, however, 4K write is a bit lower at 114MB/s. Furthermore, it reaches 79K IOPS read and 77K IOPS write, which is a bit below the manufacturer’s rating in terms of read performance, but greater in terms of write.

This AS SSD Copy Bench test is a true to life evaluation of performance as AS SSD creates three files (ISO/Program/Game), and simply moves them from one part of the SSD to another, recording their top speed and total transfer time. The best speed of 499MB/s was achieved via the ISO test. These results overall are similar to other TLC SSDs, however, during the Game portion, the result is a bit slower than what we have seen other SSDs achieve.

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 shows that performance is similar to that of our other tests. An overall score of 4875 was achieved, which is pretty good compared to the competition. Here it reached 67K/83K IOPS read/write as well.
