Announcement: Despite the circumstance that the rating of a product is based on as many objective facts as possible there are factors which can have an influence on a rating after publication. Every autor may perceive data differently over time whereas one possible reason for example is a deeper background knowledge or understanding of certain processes. Certain unforseen market conditions as well as changes have the potential to render a descision made at a certain point in time obsolete.

A closer look at the sequential thoughput rates reveals that this drive offers what you've come to expect from SandForce drives these days. Regarding sequential reads we see a maximum value of 543 Megabytes per second. Concerning sequential writes the drive tops out at 508 Megabytes per seconds. When it comes to random IOPS we measured more then 25'000 IOPS for 4k random reads and about 66'000 IOPS for 4k random writes. According to the specs this drive should be able to deliver 550 Megabytes per second when doing sequential reads and 505 Megabytes per second when it comes to sequential writes. Therefore ADATA doesn't make empty promises with their XPG SX300 SSD. What you have to know about SandForce based SSD is the fact that struggle a bit with non compressible data, which means that only with compressible data you'll be able to reproduce our performance values.

Recommendation

If you're looking for a fast mSATA SSD out there, then you should definitely consider ADATA XPG SX300 SSD with 128 Gigabyte. It is a solid option to go for and you'll definitely have more fun using your notebook or desktop PC once this drive has been installed.
