That’s not a great starting point and it’s only made
worse by the fact the UV400 has a markedly lower
capacity than the MX300 – 480GB vs 525GB.
As for that feature set, it’s an entry-level 2.5in SATA
model that uses TLC planar NAND. As such, it has
modest performance figures, particularly for the
lower capacity models.
This 480GB version has decent sequential
speeds of 550MB/s read and 500MB/s write, as
well as a reputable 90,000IOPs random read.
However, its random write speed shows why it’s
considered such an entry level model – it hits just
35,000 IOPs. That’s still far faster than any hard
drive, mind, which measure in the hundreds of IOPs.
If you can find it for £100 or below, this drive is a
decent buy for an entry-level SSD, and you’ll still get
fast boot, app load and game load times. But if you
regularly move big files or work on IO-intensive apps
it’s not the best choice – by spending
only a little more you can get much
better performance for the money.Kingston’s UV400 should be the cheapest drive on test both
based on past pricing and its feature set, but at the time of
writing price fluctuations mean it’s more expensive than the
Crucial MX300 in the UK – in the US it’s still a little cheaper.70 %
