Stan wants to clear off his DVR with a 2 Bay RAID to save his programs. But his beef is that there isn't a lot of documentation. Leo says don't worry about all that. Just use the PC settings. You can also use a DROBO, which allows you to hot swap drives if they fail so you don't have to stop it from running. But two drives isn't best because it's mirroring and you will only get half the capacity since they're identical. Leo prefers RAID 5 with three drives which gives you 2/3 storage 1/3 redundancy. It's robust. Companies that make eSata RAID 5 include Drobo. Synology is a brand that Leo really likes and it gives you a lot of flexibility to watch programming on any computer in your network.
