ADATA XPG SX900 (128GB) Review: Maximizing SandForce Capacity


SandForce sets aside more NAND capacity than most controllers for spare area. While Intel, Marvell, Samsung and others default to ~7% of total NAND capacity for spare area, SandForce is almost double that. The difference boils down to RAISE,...

If you've seen one SF-2281 drive with synchronous NAND, you've seen them all. From a performance perspective, the ADATA XPG SX900 is as fast as every other SF-2281 SSD with synchronous NAND. The only thing that separates ADATA from the competition is...

In closing, the 256GB ADATA XPG SX900, coming in at 129.99 USD as of this writing, is an SSD worthy to be on your list. Surely, there are small nuances about its random read performance but those are over shadowed by the drive's exemplary performance...

Solid state drives are slowly transitioning from a high-end luxury component to a staple of any build. They offer extremely high performance, low heat and power consumption, and are silent. The problem of course has always been the price, but as the...

?The XPG (Xtreme Performance Gear) family of products has been expanded to include solid state drives, and the XPG SX900 SSD is a perfect match for the performance requirements of this elite group. Its maximum sequential read and write speeds are...

ADATA XPG SX900 128GB SSD Review Redux


It is important to note that the differences between the two revisions of the ADATA SX900 can be attributed to many more factors than just firmware revisions alone. The previous SX900 had a much different layout with the PCB and NAND, and the NAND was...

ADATA SX900 128GB SSD Review


The ADATA SX900 128GB SSD came to us with a surprise under the hood, the new B02 version of the SandForce SF-2281 controller. This new stepping is designed to provide revolutionary improvements in power efficiency with no loss of speed. We test the...

At this time, it would be impossible for us to recommend the ADATA SX900 128GB SSD to our readers. A drastically out-of-date firmware needed to fix the essential TRIM function has not been released to ADATAs customers, even though the fix, and other...

ADATA XPG SX900 128GB SSD Full Review - Low Cost SandForce


The ADATA XPG SX900 launched mid last year, and was ADATA's first crack at the eXtended capacity variant of the SandForce firmware. This traded off some of the spare area in the interest of more capacity for the consumer.

ADATA XPG SX900 128GB SSD Review


ADATA's SX900 series is touted by ADATA as “The Most Powerful SSD on Earth”. To be fair this drive was introduced a while back so this claim may not hold all its water today. ADATA is the first SSD manufacturer to offer LSI SandForce based drives with...

If you've been paying close attention to solid-state drives over the last few years, you'll know that third-party SandForce controllers, such as the SF-2281 model in ADATA's XPG SX900 drive, have become very popular. (In a nutshell, the controller can...

Slightly higher capacity than other SandForce drives ; Accessories include bay adapter, helpful software

Error correction disabled for slight capacity gain ; Faster drives available for less

ADATA's 128GB version of its XPG SX900 is priced like a premium drive but performs more in line with a mainstream model. Still, a strong accessory pack and good bundled software add value. Whether it's a good buy depends on whether you need the extras.

ADATA SX900 128GB SSD Review


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...

Included license key for Acronis True Image HD software ; Up to 550MB/s read and 520MB/s write ; TRIM support ; 2Xnm MLC NAND

Not the cheapest cost per GB ; Other, perhaps faster, 128GB drives can be purchased for the same price or cheaper

With the ADATA SX900 128GB SSD, we got to see results that came really close to what the drive was rated at. Our fastest readings peaked at a little over 550MB/s read and 510MB/s write. The testing hit the specified read figure, but came short by only...
