I use the Super Talent 32 GB SSD
for OS X. Performance is good enough, but there are constant 5 second + pauses when browsing or doing anything for that matter. That makes the Mini9 not as usable as it should be.
I got the idea to try using a RAM drive/disk in OS X. I have a 2GB stick and there is plenty of RAM to go around. I used Esperance DV. There is a significant boost in performance. Apps launch within one bounce. Safari is quick and the machine is much better overall. I recommend those with the slower SSDs try it out.
For those unfamiliar with a RAM drive/disk. There was an option in OS 9 where you could dedicate a portion of your ram as virtual drive and launch apps from that drive, instead of a regular HD. Considering RAM runs markedly faster than a HD, then there is an overall speed improvement for those apps running off the RAM drive.
