Nothing fancy, just a linear concat of some 3TB+1TB disks, though it may eventually get upgraded to a raid5 of 3TB disks. I've figured that if I lose three disks all within the 5 hour time it takes to do a full rebuild, I probably have larger problems to worry about than losing my collection of random linux isos, even more random downloaded files, debian apt mirror, one copy of my important backed up files, and miscelaneous media files. I'll be running with the bitmap enabled, so if there are minor problems, the array will take minutes to resync rather than hours. Also, since I've gotten decent power supplies and UPSs, I haven't had very many issues with harddrives. I personally haven't had a drive failure that wasn't within the first couple weeks of purchase in years. And I always try to make sure to stress test disks before putting them into service to weed out SIDS. This way I get the 10TB+ I was aiming for when I decided to build a NAS. In raid6, I get 9.2TB or so.
