Just thought I would point out that a 2-channel 3ware card is about the price
of a single 80GB drive. (i.e. $130 US)
I love the 3-ware cards and they are not cost prohibitive in my opinion. My
only problem is I wish the failure/rebuild process was more automated than it currently is.
Obviously, LVM and MD should still work together regardless.
