You may want to consider testing the LSI 9211-8i for a very fast JBOD controller or the 9260-8i for an equally fast RAID5/6 card. I've been very happy with these controllers and they are typically much cheaper than the equivalents from ARECA. Just make sure to use the latest drivers and firmware as LSI has been improving SSD performance by leaps and bounds in the last year.

On thing I noticed with the X-25M G2s is that if you are in a write intensive environment they will degrade in performance dramatically. The SandForce SF1200/1500 drives seems to handle garbage collection much better and run with lower write amplification levels. I've found that the SandForce drives do a much better job at maintaining acceptable random write performance after months of being beat on. That all being said a beat to hell X25-M is still 10 times better than a spinning disk.

If you want I can run an iometer batch or figure out tiobench if you'd like some runs on the 9211 or 9260 to compare with your ICH and Adaptec runs. Ping me at gomeler at gmail if you are interested.
