Pros: VERY customizable. Currently, I have 3 drives rotating every month: two are connected at all times and the third is at my bank. Since RAID is not perfect, I have an auto backup every week from one drive to the other on top of rotating once a month (the swap is REALLY easy to do). I have used FTP, SSH, torrent, and all have worked flawlessly. Highly recommended especially if you're not afraid to tweak it.

Cons: None.

Overall Review: I sleep much better at night now that I have three copies of all my important data (especially since one is in a vault at night) :-)

Pros: Plug and play. Newegg packaged them very nicely so I am not concerned that anything was damaged during shipment.

Cons: None

Overall Review: I bought 3 for my Dlink 323 and I swap once a month without a hitch.
