Just thinking outloud really - and pondering switching my Buffalo to a ReadyNAS Duo (2x 2TB, running RAID0 for 4TB total) How I use my Buffalo; - simple file storage (all music, movies and pictures are stored on it, and some docs, and other files I don't want to keep locally) - iTunes on Mac and XBMC on ATV stream music and video over SMB (wired and wifi) - BitTorrent client on the NAS Other than that, I don't use any other features. No need (at the moment) for DNLA, the iTunes Server on it is crap, I have a separate back up solution (2TB USB drive) and I don't bother with Time Machine on it (plan is at some point to get a 500gb Time Capsule purely to handle Time Machine backups, as well as being a router upgrade for gigabit LAN and wifi-N) But ebuyer have a deal on ReadyNAS Duo's - £300 for one with a single 2TB and a free extra 2TB drive. SO got me thinking, £300 for 4TB and a new NAS box. I could pick up 2x 2TB to sling into my Buffalo for £220 (which is still expensive compared to what they used to cost) but would I be better off with a ReadyNAS? How reliable are they? I used to get fan errors all the time on my Buffalo, and I've had one disk failure, which although isn't the Buffalo's fault, has got me thinking about a newer, better, NAS. The ReadyNAS does AFP (which although the Buffalo says it does, I still only seem to get SMB for my NAS in finder - and I on'y have the choice for SMB in XBMC, but I think that's an XBMC limit more than anything) Worth the outlay and switch?
