Re: nas advice needed
If you have another PC and a bunch of hard drives laying around then i would use something like FreeNAS, Openfiler or Unraid nas servers. I personally use a 4TB FreeNas in a raid-z2 on a gigabit network to backup all my media and files. Its writes way faster than any Qnap/drobo out there (Unless you are willing to spend thousands).. The money you would save by building yourself a free nas server you can uses it towards buying storage.
both Freenas and openfiler support the following..
Network Protocols supported:
Bittorent client (Transmission)
UPnP server (FUPPES)
iTunes/DAAP server (Firefly)
Network bandwitdh measure (Iperf)
Hard drive / volume management
ZFS (FreeNAS only)
Software RAID 0,1,5 and mix (1+0,1+1, etc…)
Disk encryption (using cryptographic accelerator card if present)
Filesystem: UFS, Ext2/3, FAT, NTFS
Partition: MBR and GPT
802.1q vlan tagging
Wake On Lan
