Yes, the Accelsior is my boot drive. It has my apps and scratch space as well. My home directory is on my striped WD Blacks, as I have a lot of data there.
EDIT: Ignore the rest of this post. Take a look at my updated performance tests. The Accelsior blows the doors off anything else I can imagine. Either that or I have a bad Accelsior. I will update when I know more. The jist is that I should be seeing similar write speeds to read speeds. OWC quotes: Sustained Data Transfer Rates of up to 780MB/s read and 763MB/s write"

I like the Accelsior a lot, but I am a little discouraged by the write speeds. I need to use some other speed testing tools to test it. I have seen it hit 240GB or so write in real world applications from time to time. It certainly never feels slow by any means.
The read speeds are incredible, of course. Also, it was very easy to set up. Just slap in a slot and you have a drive up and running.
If I had to do it over again; I would strongly consider an OSX striped pair of 120GB SSDs. It would give me twice the storage, and I don't think would really be that much slower for a lot less money. Or I should have been patient and waited a few more weeks for the 240GB Accelsior.
I do have to say that I am a big fan of OWC SSD drives though. I have had a lot less issues with them than other manufacturers; and they do a good job of supporting their drives when problems do arise.
If there are any specific performance tests you would like me to run; feel free to ask.
