I have an Agility3, another SF-2281 controlled SSD, and I'm pretty pleased with it. I did have one hiccup (random BSOD's) that I thought were memory related but now I think more SSD related. I did ckdsk and now all is well...
I still think the SF-2281 is a pretty solid controller (at least in my experience,) and much depends on manufacturer FW, it's application (RAID, etc) and how it's used (I don't sleep or hibernate.)
Do I trust it? Yea, sort of. I do W7 backup images once a month, along with weekly data backups (something I should be doing, anyway, regardless of drive.) I'll be upgrading from the 60GB A3 soon, but I'll probably go with another SSD (I really want a Plextor M3...) when I do. Reliability is paramount, my desktop is my and my wife's business computer... if the comp BSOD's when shes using it, I'm likely to find it in the middle of the street with tire tracks on it. My wife isn't very tolerant of computer problems.
