ADATA XPG SX900 128GB SSD Full Review - Low Cost SandForce
IOMeter v2006.07.27 - IOps
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 - since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
Light desktop usage sees QD figures between 1 and 4. Heavy / power user loads run at 8 and higher. Most SSD's are not capable of effectively handling anything higher than QD=32, which explains the plateaus.
Regarding why we use this test as opposed to single-tasker tests like 4KB random reads or 4KB random writes, well, computers are just not single taskers. Writes take place at the same time as reads. We call this mixed-mode testing, and while a given SSD comes with side-of-box specs that boast what it can do while being a uni-tasker, the tests above tend to paint a very different picture.
The ADATA unit uses the base SandForce firmware, and therefore lags behind the custom firmwares offered by Intel and OCZ. The sync flash does enable it to beat out the async flash equipped Corsair Force. The OCZ Vector and Samsung 840 Pro show their dominance in this area by easily putting all SandForce parts in their place.

Firmware 5.0.2a still has issues and they were resolved in 5.0.3. The newest SandForce firmware is 5.0.5 and it's very good. Too bad ADATA can't get their firmware act together.
I have tested my SSD with newest SandForce firmware 5.0.5
Having troube on that one as well. B-S-O-D :(
You guys can download IOMeter 2010 from
http://sourceforge.net/projects/iometer/files/iometer-devel/1.1.0-rc1/
Play around with it and tested 4K random write via IOMeter 2010
See if you have same test result
32G SSD => BSOD, 0xF4
64G SSD => BSOD, 0xF4
bty, can someone tell me where we can download 5.0 B?
One of my friend said 5.0 B will be available shortly.
Is this truth?
I think I'm going to get this SSD for my next build, looks promising and good for the price! I'm a casual PC gamer!
ADATA just releases updated firmware for SX900 SSD drive. It is now at Firmware 5.0.7a

Adata Firmware 5.0.7a release notes do not metion anything about TRIM being fixed... WTF?
"ADATA first with SandForce 5.0.7a firmware, TRIM enabled for ADATA SSDs"
This is the headline I've been seeing, I assume that TRIM issue have been addressed and that this update has fixes found in previous firmware except the one that was pulled from breaking TRIM.
Purchased 2 drives in January 3013. Went online to get info on how to properly setup the OS (enable TRIM etc). Also used the wipe free space feature of ccleaner. CrystalMark always gave me good results except for write speed which is around 250 instead of 500 like the read speed.
Bottom line, I had the expected performance even without this firmware. I'll install it tonight but cant see myself getting much of a boost (write speed).
