I just completed my changeover to home NAS. I was very lucky to have stumbled across the D-Link Forum. There is a lot of knowledge in these pages and some very knowledgable users. From the advice on this forum I set my DNS-321 with firmware v1.01 before I setup my Deskstar 500GB drives in a Raid-1 configuration. I have 5-users so I spent a little time setting up folder access. This wasnt going well until I removed everything from Volume_1. I then setup myself as the only one who had R/W access to Volume_1. I then created a group user folder structure and then assigned the desired user access levels and restrictions. I then ran several speed tests and was quite impressed. Satisfied with R/W speeds I went ahead and re-mapped everyones "My Documents" folder on their windows PCs to their individual NAS "My Documents" folders. I went ahead and made a single point for shared music, video, and movies. I have to give it up to D-Link: how great is it that they support (via software) the ability to run the DNS-321 as a gaming server (without a static account) over comcast! Since I am using the D-Link NAS as a file server instead of a "backup" device I was a little concerned about bottlenecks - I have 3-wired users, 2-wireless users, and 12-wireless-other devices on my Linksys N router. I have not noticed any performance issues. I had to map Volume_1 as N: so I could stream off the NAS for DVD backup burning. I am very impressed with DNS-321 and drives for under $200.00, WOW!
