Sounds good. I've heard good predictions about LSI (most notably by
Digimer and John, and now Gordon sounds really encouraging). How about
Areca? They seem to have support for 4kn drives, are they going to be
another option for us, hardware RAID people? Their creatures were pretty
good so far in my book...

I do my best to stay away from those who ever released "fakeraid" chips
(or "software RAID"), the ones relying of "driver" (read: your system and
CPU processing RAID functions). Meaning here adaptec ;-(
If I were to do RAID without dedicated RAID card, just export me the
drives, and my system has all necessary for that.

Thanks a lot for all your insights!
