I'm looking at getting an external storage solution and could do with some advice. I want something that can hold 2 drives minimum and I've narrowed it down to 2 pretty different options. First, we have the IcyBox NAS4220 which is £105(ish) but as well as being a NAS hard drive, it has an itunes server, FTP server, Bittorrent server, etc all built in. Second, we have the IcyBox IB-3218StU which isn't a NAS (only USB), but it does have JBOD (which the NAS does also) so I can access both hard drives seperately through a single USB cable. What are the transfer speeds like on a NAS (typically)? I'm trying to decide whether or not I will use the Nas features (mainly accessing it on more than one computer) which I may do, but I'm under the impression I can share any drive anyway, regardless of whether it's connected to a router or a Mac? I guess the only real difference is the I wouldn't have to let my computer on with a NAS. Anyway, which would you go for?
