Our short term solution is to go with two Buffalo TeraStation Pro II, 2 TB NAS devices. I have heard some good things about them and their price tag is hard to beat (about $0.50 a Gig!).
So we are running both of these in RAID 5 and backing up from one of them to the other.
- Rack Mount
- Several RAID levels including RAID 0, 1, 5, 10 and JBOD
- Web management
- DFS and automated backups
- FTP and AFP support
- The management of the hard disks and RAID doesn't have as many features as I would hope.
- Buffalo's implementation of DFS is a far cry from what you get in Server 2003 R2. You also can't throttle the synchronization bandwidth.
- The documentation is OK but you can tell that it has been translated and it doesn't go into much detail on DFS or FTP configurations.
- When you join the unit to Active Directory you can't use FTP anymore.
- Only one NIC
