ADATA XPG SX950 240GB SSD Review

Although the SX950 is ADATA’s first XPG branded 2.5in drive to use 3D NAND, the company have embraced the latest NAND technology fully and it can be found in both MLC and TLC guises throughout its ranges of 2.5in, M.2 and external SSDs.

The official headline Sequential performance figures for the 240GB version of the XPG SX950 are up to 560MB/s for reads and 520MB/s for writes which we were able to confirm with the ATTO benchmark. When tested our review drive produced a read performance of 563MB/s and writes which at 532MB/s, were a wee bit faster than the official figure.

We couldn’t quite match the official figures when it came to 4K random read/write IOS performance. Under our IOMeter test configuration, the drive produced 71,454 IOPS, which was a bit below the official 80,000 IOPS. The write performance, however, was a lot closer to the official 90,000 IOPS at 88,468 IOPS, which is incidentally the fastest write IOPS performance we have seen to date for a consumer drive in the 240/256GB bracket.

The SSD Toolbox is a useful utility that lets you perform most of the maintenance task you might need for an SSD as well as informing about the drives well-being and how the capacity is being used.

ADATA back the drive with a useful 6-year warranty.
