Features    [ Edit | History ]

The XPG (Xtreme Performance Gear) SX900 solid state drive is an expanded capacity SSD which uses new optimized firmware to utilize greater storage capacity of the NAND Flash components. With superior NAND Flash, the XPG SX900 SSD reaches new levels of stability and performance. The drive breaks new ground in storage capacity for SSDs utilizing the SandForce 2281 controller, reaching 512GB, a 7% increase over common SSDs in the market that use a SandForce controller. This represents a milestone in ADATA's history of NAND Flash based products.

Super full capacity with high performance
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 550/530 MB per second, with maximum random 4k write speeds as high as 85,000 IOPS. With capacities of 64, 128, 256, and 512GB, the XPG SX900 SSD is poised to take its place as a market and performance leader.

Supports Windows TRIM Command, Accelerated Data Transfer Performance

The XPG SX900 SSD adopts specially selected Flash chips from reliable manufacturers, and supports the Windows TRIM command. The Windows TRIM optimization command can directly delete stored data in the Flash memory and release unused space (Free Blocks) to be used for system writes immediately. This results in more accelerated transfer and write performance for solid state drives, and is also effective in slowing down efficiency decline and depletion chances, maintaining effective operation and extending the life of the disk. In both desktop and notebook computers, users will enjoy an unprecedented high-speed experience when they edit video, retouch large picture retouching, and use computer drafting, reading and writing operations.

Like getting a new computer, boots and runs faster,This is my second Adata drive very pleased. Nice and quite as there are no moving parts.
No big deal but adapter does not fit my Sonata case
Looks nice and works very well probably will get another for my spare computer.

Experience: 14 Days
Includes 3.5" to 2.5" adapter
Good price when on sale
No cloning software or key for one
Picked this up to perk up an older laptop my mom had. What a difference! The old 5400rpm drive took over 2 minutes to boot up Windows 7, but with this drive it is under 15 seconds. Everything is faster now; web-surfing, mild gaming, opening new windows. Very happy and it breathed new life in an older system so we don't have to spend all that money on a new one. Highly recommend.

Low cost
Fast Speed
Comes with brackets
Didn't have a SATA cable but those only cost $3.
I bought this to speed up my old beast of a computer along with a ram upgrade. It's like having a brand new computer. The SDD is the best purchase I've ever made and even better is that it was 25% off when I picked it up.

-Price for space
-cloning sofware
-3.5in adapter included (Not that many people use this anymore)
-None so far
I purchased one of these for my original rig which I have since passed down to my wife for photography editing.

I can't be sure, but I believe I picked up that hard drive a year after getting my first rig, which makes it 4 years old at this point. It is still going strong.

I bought two more of these for my new rig, both have worked well so far, no issues. Based on the 4 years of solid use; gaming every day, downloading regularly, etc, and now my wife is uploading photos constantly, the original one is still going strong. Solid thumbs up!

Comment: This is a review which exposes some questionable and also odd issues with SX900 SSD's. Adata has significantly changed the hardware without even changing the sku let alone the model name, and has used some generic NAND that nobody knows anything about. If these firmware issues have been fixed, t
