Its funny that you had such bad luck with the Burly boxes. I have 2 5 bays with 1 TB seagates, and a cal dig host card (on a Mac dual 2GH.
(cal dig card is great but discontinued for PCI-x). Very fast, not a single problem untill my raid 0 went down, I knew that was a bad idea. I will say that the one drive in the raid failed at the exact moment the overtemp alarm went off, and it was set to a low 104 degrees, so it wasnt the heat.
Any way, the burly boxes are very big, and the fans are very loud, so I bought 2 new firmtek 5 bays and a firmtek host, and some 1.5 seagates. So 7.5 TB’s of storage for about 1200.00. I will use this for my home system and BU (better late than never- lesson learned). The firmteks are small and very quiet, but I have been wresling with them for days. I am now considering buying 2 more Burly enclosures although I would really like to keep the Firmteks.
I will say that you should definately heed the good advice I have seen on this forum regarding raid 0. Eventually, the raid will go down, Just be sure to have a dupe set of media when you do. With that secuity you can run faster than raid 5, at significantly less cost, even including the price of extra drives.
