Kingston SSDNow UV400 480GB SATA III SSD Review

Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. With ATTO, we are looking at maximum sequential performance with compressible data.




Compressible sequential read/write transfers max out at 547/530 MBs. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. Performance gets a bit choppy when the drive is loaded up with data. Maximum sequential performance is achieved at 512KB transfers.


Sequential Write




The UV400 displays choppy write performance when the drive is loaded up with data. This is common behavior for many planar TLC SSDs; the BX200 is an extreme example of choppy write performance. Overall, the UV400 is running in the middle of our test pool.



Sequential Read




Read performance smooths out somewhat, but it is still a bit choppy for our liking. The UV400 runs in the middle of the pack up to 4KB transfers. Beyond 4KB transfers, the UV400 is outperformed by the rest of the test pool.




Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16. With Anvil's, we are focused on the total score.








Anvil's scoring typically provides us with a good indication of a drive's overall synthetic performance. The UV400 returns a good overall score. We want to see a score of 4,500 or higher from a planar TLC drive - the UV400 scores almost 4,900.


(Anvil) Read IOPS through Queue Depth Scale




The UV400 outperforms the BX200 and the SP550. The Phison S10-powered drives in our test pool easily outperform the UV400.


(Anvil) Write IOPS through Queue Scale




At first glance, the UV400 looks to be the losing across the board. However, if we take a close look at the UV400 at QD1, we see that the UV400 is delivering the best QD1 performance of the bunch. We consider QD1 performance to be the most important of all the queue depths measured.
