At an end, it has SATA power and data connections. It drive is powered by the Marvell 88SS1074 SSD four-channel controller and has Toshiba 15nm 2D planar Triple-Level Cell (TLC) NAND. It has Nanya 512MB LPDDR3 DRAM cache chip.

Benchmarking results

These are benchmarking scores recorded on few disk benchmarking tools.



Here see how speed dropped to around 100 Mbps.


This is because it is the typical TLC-based SSD. You will see this lower data transfer speed if you copy a large amount of data to the drive without any idle time. Once the device is idle, it clears the cache to offer you better speed again.

Final words

You could get better SSD for this capacity, but this is a solid value for money product and affordable. It also worth to note that performance of the other UV400 SSDs decreases if you go with low-storage models of the same product. You will not get good performance numbers but this is not bad considering the price of the product.

The only disadvantage of the drive is that it relies on the SLC cache and this issue is with all TLC-based SSDs. So, write speed drops dramatically once the cache fills up. This only appears if you are doing longer writes that are the transfer of 6-8 GB file.

This drive is backed by 3-year warranty and we know that Kingston is good in after sale support.

Overall I am satisfied with this Solid State Drive and recommend you if you do not want to spend more.
