Reviewer's Opinion

The ADATA XPG SX900 128GB SSD performs well in all tests and is available at price below $1 dollar per GB. At the price and size, the SSD is the perfect upgrade for a desktop machine, especially considering the included disk imaging software and 3.5” desktop bracket. With the price of SSDs continuing to fall and the increased speeds, inevitably they will be in every modern system as the boot drive. Unfortunately, with the size of most affordable SSDs space still needs to be conserved so a user needs to choose wisely what to install on the drive and what to put on a mechanical drive.

One of the beauties of SSDs is that they run cool, efficiently, and silently. This is a major plus, considering that temperature, energy usage, and noise are the enemies of most system builders. The ADATA SX900 using only 0.5 watts of energy idle and 1.2 watts under load proves to be energy efficient and thanks to that runs cool. Of course, since there are no moving parts, it also runs without adding any noise to the system.

In all tests, the ADATA SX900 performed at close to the same level or outperformed the comparison drives. In the tests where the SX900 was outperformed, the difference was such a minor amount that it would not be perceivable during normal use. The only test that produced an anomaly was IOmeter where the SSD scored less then expected. Unfortunately, the IOmeter test can favor certain drives based on the different controllers and NAND used in SSDs. In this case, we believe this is what caused the lower numbers. In the real world file transfer tests and application load tests, the drive performed very well, speeds were significantly higher than mechanical drives and on par with other SSDs.

Overall, the ADATA SX900 series SSD is priced well and has the performance to compete in the high performance market. The exterior of the drive is aesthetically pleasing with its black brushed aluminum finish and casing is solidly built. Efficiency, temperatures, and silence have been a focus of system builders and enthusiasts alike. The SX900 meets these demands by running cool, using very little energy, and maintaining peace and quite. The ADATA XPG SX900 128GB SSD earns the HiTechLegion Gold award, thanks to its price to performance ratio and bundled accessories.

*update* We have been made aware that there is an issue with the SandForce controllers and some firmware revisions, where the TRIM function of the drive can fail and the drive will degrade over time. In our three weeks of testing, we did not experience any degradation that could be attributed to TRIM. In future testing, if we do experience degradation, we will update the review.
