Dlink DNS-323 and Western Digital WD15EADS Caviar Green 1.5TB

I bought a NAS, Network-attached Storage.
Actually I bought two items. One is the NAS enclosure, or Dlink DNS-323, 2-Bay Network Storage Enclosure. It is a very old product. Start to sell about two years ago. The other one is a Hard disk.
Western Digital WD15EADS Caviar Green 1.5TB. It is a SATA 32MB Cache 3.5IN Hard Drive.
I put one disk in it. In the future, if I need, I can add another 1.5TB in to double the capacity.
The features of DNS-323 are so many and a lot of people talked about it. I don’t want to repeat it. You can google it.
The point I purchase this kind of toy is based on following thoughts.


1) Storage for digital photos, DV
2) Backup space for my desktop
3) Power consumption
4) Noise from fan
5) Expend or hack ability.
