Excerpt: Unless you're sporting really old hardware, an SSD is the best sure-fire way to boost the performance of your desktop or laptop computer. There is so much choice now it's difficult to know whether there is a significant difference between various SSDs and which one is the best for you. Well, you've come to the right place. We tested 36 recent models.
Conclusion: The ADATA XPG SX900’s performance was very good, if somewhat uneven. On the one hand, it posted best-in-class scores in PCMark 7 and did very well in ATTO and (for the most part) in CrystalDiskMark tests. Its HD Tune scores, by contrast, were inconsistent, and it had trouble with some write tests as well as the IOMeter default access pattern. Overall though, the performance of the ADATA XPG SX900 is among the best of the SandForce-based drives we've tested.
Pros: Price, Makes better use of NAND Capacity, Top performance in some tests, 7mm Z-Height
Cons: Somewhat uneven performance, Same SandForce issue with incompressible data
Summary: Our original review of the ADATA XPG SX900 ended on a sour note. Unreleased critical firmware revisions and unexpected power consumption figures led us to question ADATA's customer support. Today we take another look with a fresh sample and a new firmware revision that ADATA has made available to its customers.
Excerpt: We're looking at the ADATA SX900 for the first time today. The SX900 hit the market with the SP900 last year, but the SP900 review didn't go as ADATA planned. Just days ago ADATA fixed their issue with TRIM by releasing new firmware for a number of SandForce SF-2000 based SSDs. The new firmware, 5.0.7a, is new to us. We expected ADATA to launch 5.0.6, but they leaped straight to this release, one that we didn't even know of prior to ADATA handing it out.
Excerpt: With newer and faster SSDs coming to market, we should not forget those capable controllers of yesteryear. There are plenty of folks out there cranking out products based on controllers that were until very recently the king of the hill. Competition is great for the market, and newer product launches have driven down the cost of the older SandForce 2281 SATA 6Gb/sec controller.
Summary: The ADATA XPG SX900 is another in a sea of SF-2281 drives that gives solid performance at an affordable price point. Owners and potential buyers of this and similar drives running firmware 5.0.2a should be watchful for the updated firmware that will correct the TRIM issue.
Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete.
Pros: Outstanding 558/532 MBps read/write speed with ATTO, Produced 80,000 combined 4K IOPS, Among the most affordable SSDs available, TCG OPAL security with 256-bit AES encryption, Uses synchronous NAND flash components, SandForce SF-2281 processor supports TRIM, SMART, and RAISE, DuraWrite technology extends NAND lifetime, Enthusiast-level operational I/O performance, 3-Year ADATA product warranty support, Available in 64/128/256/512GB storage capacities, Lightweight comp...
Cons: Limited company support, Expensive enthusiast-level product
Conclusion: Final Words 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 the fact that they have disabled RAISE and hence offer 8GB more capacity than other drives. Since we are dealing with such similar drives, it all boils down to price.
ADATA XPG SX900 256GB SATA 3 SSD Review – Expanded Capacity and SandForce Driven Speed
2 April 2012
Conclusion: It is not often that we cut right to the chase but this has to be one of the most refreshing SSDs tested in quite some time. In fact, it was received at 3:00pm today and I haven’t been able to take my hands of it yet. It’s like getting into a good book that you just hate to put down. When we posted the LSI SandForce release back in February, even I wouldn’t have placed my money on performance not being lost for capacity gain. There is always give and take after all.
