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

Subject: Storage


For these tests, we use RankDisk, an application developed and copyrighted by Intel. In our testing, we found RankDisk to be suitable for a neutral benchmark. RankDisk is used to record a trace of disk activity during usage of typical applications. These traces can then be replayed to measure the performance of disk operations for that usage.

RankDisk records disk access events using the device drivers and bypasses the file system and the operating system's cache. This makes the measurement independent of the file system overhead or the current state of the operating system. In replaying traces, RankDisk always creates and operates on a new dummy file. This file is created in the same (or closest possible) physical location of the target hard disk. This allows the replaying of traces to be safe (does not destroy any existing files) and comparable across different systems. Due to the natural fragmentation of hard disks over time, they should be defragmented before running these tests.

The traces used for each test were created from real usage. The traces contain different amount of writing and reading on the disk; total ratio in the HDD test suite disk operations is 53% reads and 47% of writes.

The following input traces are used:

Windows XP Startup: This is the Windows XP start trace, which contains disk activities occurring at operating system start-up. The test is 90% reading and 10% writes. This trace contains no user activity.

Application Loading: This is a trace containing disk activities from loading various applications. It includes opening and closing of the following applications:

Microsoft® Word        
Adobe® Acrobat® Reader 5        
Windows® Media Player        
Leadtek® Winfast® DVD        
Mozilla Internet Browser

The application loading trace is 83% reads and 17% writes.

General Hard Disk Drive Usage: This trace contains disk activities from using several common applications.

These are:

Opening a Microsoft® Word document, performing grammar check, saving and closing        
Compression and decompression using Winzip        
Encrypting and decrypting a file using PowerCrypt        
Scanning files for viruses using F-Secure® Antivirus.        
Playing an MP3 file with Winamp        
Playing a WAV file with Winamp        
Playing a DivX video using DivX codec and Windows® Media Player        
Playing a WMV video file using Windows® Media Player        
Viewing pictures using Windows® Picture Viewer        
Browsing the internet using Microsoft® Internet Explorer        
Loading, playing and exiting a game using Ubisoft Tom Clancy's Ghost Recon

The General Usage trace is 60% reads and 40% writes.

Virus Scanning: Virus scanning is a critical task in today's PC usage. As the major bottleneck of scanning viruses is in hard disk activity, it is reasonable to include virus scanning as a HDD test. The test consists of HDD activity of scanning 600MB of files for viruses. The Virus Scanning test is mostly disk reading (99.5%).

File Write: This trace contains disk activities from writing 680MB files on the hard disk and no read operations are involved in this test.

PCMark replays a pre-recorded trace of IO back on the drive under test. This is one of the more real-world ways of testing, its weakness being that it is more of a short-term test and might not represent long-term usage of an SSD. We mitigate this somewhat by pre-conditioning the SSD prior to the test.

ADATA performs just as well as the other SandForce SSDs in this test. Newer models perform better, but only marginally.

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

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?

April 15, 2013 | 02:09 PM - Posted by Anonymous (not verified)

"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).

Actually I think this is among the most vital information for me. And i am glad reading your article. But want to remark on some general things, the web site style is ideal, the articles is really excellent. Thank you for sharing with us. I think it would be effective for all. Good job, cheers! invites you to read
