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.

- fast
- light
- not expensive for an SSD
- did I mention fast?
none so far
This SSD is super fast! Then again, I came from a regular HDD. So any SSD will be fast. Haven't had any data loss (knock on wood). Would recommend this product.

Experience: 5 Months

Lots of Storage
Good Performance
Adapter bracket uses non-standard drive screws
Other than my installation issues, everything else has been flawless. 3.5 inch mounting adapter uses a non-standard threading which means the screws for my Antec 900 case would not work. They are threaded in a hard metal insert, so I had to drill holes in the plastic for screws to mount it.

If you have your own bracket, standard 3.5 inch mounting system, or a 2.5 inch SSD mount in your case, you shouldn't have any problems.

Otherwise performs well after 5 months. No issues yet. Still snappy with trim enabled.

I brought 10 of this drive. Replaced on all my PC and laptops.
Speed increase 3 times. Love it.

I usually rely on Kingston HyperX 3K drives, which I found to be very reliable and the performance, though not verified via benchmarking, seemed to be very good. I also use Plextor M5Pro's and I have found them to be the same.

When I saw the specs on this drive matched with the price, I had to try it. So far, no regrets.

I *did* read a review:

that mentioned:

"...The drive has been out for more than a year, and as we’ve mentioned, it’s been built with at least three different types of NAND, it has at least two differently-sized PCBs (depending on the stepping), and it’s come in two different z-heights (9.5mm and 7mm), so you might want to check model and revision numbers. Regardless which iteration of the SSD you end up with, make sure you have the latest firmware update  for the drive.

When you drop  down your money, make sure you’re buying one of the newer versions. Scan those spec sheets with an eagle eye."

I wasn't sure how to ensure that I got the latest version :\

Definitely faster than a hddrive, as advertised. Very fast bootup from cold or sleep mode.
Slower load times for multiple small files. Does not include an adaptor for hd storage on my computer case.
Not the fastest ssd drive, but definitely worth it dollarwise as a master drive for gaming vs. HDdrives.

Would be nice to have advertised that the adaptor was for a 3.5 not for internal desktop computer storage.

Experience: 2 Years

Good price for 512GB & decent speed
Very good SSD for the price running 3x of these in my system and I have no complaints what so ever.

Experience: 20 Days

Fast, price is good
Bought this to store virtual machines and some applications that needed to run fast. It definitely speeds up the loading time of my VMs. And for the price, it's definitely a great buy! Highly recommended.

Experience: 7 Days

Great price
Lightning fast
None so far
I bought this for a new gaming machine I built. I did my research and compared prices and went with this bad boy. For a boot drive you wont find better for the money.

Experience: 5 Days
 Verified Owner
Price is good
Speed is good
No software like Samsung Magician
This SSD is fast and great, work well in my laptop.
No problem at all using this SSD but i thought it was coming with a software like the Samsung SSD. That would be very usefull to help disable stuff in Windows and to optimize everything. Still able to do it manually
