Just curious as to what external raid enclosures and eSata cards people are using. There seems to be a lot results and a lot of poorly reviewed stuff out there. I was thinking Lacie but don't like that I can't run to a store to replace a failed drive. I'd like 4 drives, 2TB each in a raid 0+1, a hot spare would be nice but isn't killer. It seems eSata would be best as an interface through an add on PCI card. What do you use or would you recommend?
