There are a lot of storage solutions out there, some are simple, some are complex, and some are more reliable then the other. Usually for big Storage needs I have stuck to the Netgear ReadyNAS line as their support has been excellent and they have a nice range of items from the expensive to the reasonably price depending on your needs. Lacie have been also developing high quality external storages for sometime now, and now they have just launched the new LaCie 5 Big Network which is available in 5 TB, 7.5 TB, and 10 TB versions.
The 5big Network is fully featured with a Gigabit Ethernet connection, USB, 3 eSata, and five hot-swappable drives that support seven RAID modes, which makes it very versatile. The 5big Network’s multimedia server capabilities have been improved, now allowing users to play media from the NAS device through a UPnP-AV compatible device such as a PS3 or Xbox, directly to a television or directly to any DLNA multimedia device. Not including that is compatible with iTunes Server, moving library over and streaming all media to different computers across the network. It has been optimized for Mac & Windows backup solution with 3 Intego Backup Licenses for Mac & 3 Genie Backup Manager Pro Licenses for Windows The price ranges from $799 all the way to $1400, it is a well backed-up product with LaCie procedure to replace it within a few days of you sending it. And I think it looks very good, same sort of Industrial Design as Apple.
