Looking for a NAS, with gigabit interface (l’m done with slow access speeds via usb interface to my internal gigabit network) so as to speed up my rendering server farm file access, and expandable with support for additional sata drives and affordable. Finally settled for the DLINK DNS-321 for $130 and bought just one 1Tb SATA drive that was on sale for $87 – a Samsung 10,000rpm 32Mb buffer drive. As sata drives fall in price and l get more bang for a buck l can add to this unit. I can mirror a drive, but the unit doesnt support ntfs etc – which is fine for me since my shared files on this will be media files, mp3 and rendered jpeg pictures. It has a web interface control and can be accessed remotely via ftp anywhere on the net. This system is built on a GPL / Linux based system, and will format your drive to ext2 format. There might be a hack out there for a more native windows file system support.
Update: 5/14/09. I’m returning this item. The file transfer time to and fro ext2 to my ntfs formatted drives is so so slow, about 10-20x (even by Windows wrong estimates). The gigabit connectivity makes no noticable difference, even when on the same Cisco 5 port Gigabit switch as my server. I’ve ended up overloading my faithful dell sc430 server by “creatively” adding this 1Tb drive to it, the server is designed to support only 2 sata hard drives. See picture below.
