ADATA XPG SX900 128GB SSD Full Review - Low Cost SandForce

Subject: Storage

HDTach 3.0.4.0

HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.

Bursts are provided only for your review. SSD's don't cache the same way HDD's do (in many cases they don't cache reads at all), so burst testing typically results in figures that are lower than the sequential throughput figures.

SandForce controllers have always been a bit tricky in playing nicely with HDTach. The way it accesses the device under test makes some HDDesque assumptions that are *very* sensitive to SandForce firmware tuning. Perhaps *too* sensitive, as the differences seen above don't translate into real world differences in performance.

HDTach feeds the tested drive a continuous string of small sequential read requests. This is a single threaded operation, which means the SSD doesn't get to see what's coming next. The lower the QD=1 latency of the controller pipeline, the better the numbers we see from this test. It doesn't equate to real-world maximum throughput, but it does mean something for analysis, which is why we include these results.

Better sequential figures are present on the next page (HDTune).

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 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).
