It's been mentioned in the past that for "simple" SATA expansion cards, a good/affordable choice at this point are cards using the Silicon Image 3124/3132/3531 chips (driven by the siis(4) driver). Avoid the 3112. The reason I say that (despite not having any experience with them) is there's active development on that driver by mav@, and SI is apparently fairly forthcoming with docs/quirks. Otherwise Areca cards are a good choice, but are $$$. I personally stick solely to on-board SATA driven by Intel controllers (ICH7/9/10 or ESB), but if I had to get an expansion card, at this point I'd probably go the SI 3124 route. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
