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.

Great upgrade in my mid2012 MacBook Pro. Stock HD was a 500g 5400rpm. Things were getting slow. While not the speediest SSD out there, for my purposes, this is amazing. Obvious performance improvement. Good price too.
none at this time
Prior to swapping, I ran Blackmagic Disk Speed test, which clocked the Read/Write of the stock HD at around 25-30mb/s. The new drive hit the targets in the product description - consistently over 350 mb/s write, and 450+ read. This coupled with boosting my RAM from 4 to 16g, has me smiling :)

I've used 2 of these in Raid 0 in 3 of my machines.. though 500GB main drive is still quite low for a main drive... Its is fast.. im getting 900+ Mb/s Read Speed 870Mb/s Write speeds
None.. Id only have a Con if they didn't work or have failed on me..
Ever since I have added these to my setups.. my windows experience (in general not the rating system) has been EXCEPTIONALLY Stable. No bottle necks.. and its uber quiet. As simple as stating the obvious goes.. No moving parts makes it makes me feel they will last a lot longer than any platter HDD And that I made the right choice.. I Really recommend ANY setup in raid 0 SSD for shear speed.

It a ssd so realy fast. Came with a support for a 3.5 in hdd bays
I'm not a big fan of the logo.

Experience: 8 Months
Fast and reliable
None so far
Reinstalled Windows 7 from a 1TB 7200rpm WD Black HDD to this 238GB (usable space) SSD and load times are blazing fast. I don't turn on my PC unless I am instantly going to use it, gone are the days where I had to turn it on and go do something else while it loaded Windows. Also you can't go have a glass of water and come back before it reboots completely, it's just too fast!

At C$116 when on sale is only 45cents per gibabyte, one of the cheapest in the market whilst being really fast unlike other cheap slower and unreliable drives. (Sounds like marketing but sadly I'm not getting paid for this amigos)

Today I bought a second one for games only as I want to move DA Inquisiton to an SSD and put MGS V in one too. I loved Witcher 3, Skyrim, Rome 2, GTA V and BF4 loading times on this SSD. I'm never going back to a HDD for Windows and modern games with long or constant loading screens. I just hope this SSD lasts for at least 4 years... make it 6 :D

Fast boot, reliable
Have been using it since Dec 2013. So far no issues whatsoever.

Great drive, great price
None yet
Bought this as an upgrade in terms of speed and capacity for my Crucial m4 128gb SSD and am not disappointed so far.Got what I wanted out of the drive in terms of extra capacity and the write speeds are noticeably faster. Would buy again.

Very nice Price
I check in benchmark and somehow I didnt get that speed of transfer, but I dont blame the unit, maybe is my system.

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
