ADATA SX900 128GB SSD Review

Price: $110


Over the past few months we have seen a tremendous decrease in the consumer cost of SSDs ranging from 64GB caching SSDs to 256GB storage SSDs. As the market is flooded with more and more options for SSDs, the competition between all of the major brands drives cost to the consumer down. For as little as $0.70 per GB and lower, a computer owner can significantly increase the performance of their computer by switching to an SSD as a main drive. SSDs are also a great choice for laptops as battery life is stretched as a result of the lower power requirements.

Today, we will be checking out a 128GB SSD from a manufacturer named ADATA. The ADATA SX900 128GB SSD is based off of the SF-2281 series SandForce controller. It is specified to have read/write performance of 550MB/520MB/s and a maximum 4K Write IOPS of 85,000. So far, the SX900 series SSDs from ADATA are the fastest SSDs it has produced. SX900 series SSDs are available in sizes of 64GB, 128GB, 256GB, and 512GB. For about $110, you can purchase an ADATA SX900 128GB SSD of your own. Included with the drive is a license key for a copy of Acronis True Image, which by itself is a $50 value! Having already seen some great performance from SandForce SSDs, I'm excited to see how ADATA stands up to the competition.


Closer Look:

The ADATA SX900 128GB SSD is packaged in a slim box made out of card-stock material. A window in the front of the package lets the owner see the top of the drive, along with its yellow/gold label. Underneath this window states that the SSD comes with a copy of Acronis True Image and that there is a three-year warranty. Also on the front is a photograph of a 3.5" adapter for use in a desktop. The back of the box has a few lines of standard notes presented in many different languages. Underneath these notes is a white sticker with read/write information. It states that the maximum read performance is 550MB/s and maximum write performance is 520MB/s. This isn't an uncommon number for other similar drives on the market.







Included in the box is the 2.5" to 3.5" desktop adapter made out of blue sheet metal (hardware included), the ADATA SSD Quickstart Guide, and of course - the SSD itself.



The drive is constructed out of black brushed metal (aluminum most likely) and has a yellow and gold sticker on the top face of the drive indicating its brand name, model number, and drive capacity. Other information states that it is ROHS compliant, that it should be recycled, etc. The bottom of the drive has a warranty void if broken sticker that covers up one of the screws that hold the drive together. A plain white sticker lists the drive's specific model number, warranty code, and the included Acronis True Image HD key. The I/O and power port layout is of standard nature, along with the threaded mounting hole locations. Four screws on the bottom side of the drive hold the two pieces of the case together. One of these screws is covered up by a warranty-void sticker if removed, so don't do this at home!




The ADATA SX900 series drives are built around the SandForce SF-2281 controller. There are a total of sixteen (eight on each side) 8MB NAND flash chips that total up to 128GB. These chips can operate at up to 550MB/s read and 520MB/s write at an I/O rate of 85,000 IO/s, which are pretty standard numbers for the current market. The memory chips do not have a brand name on them; only a series of numbers and some letters.
