Here are my favourite additions to the DNS-325 functionality:
1. S.M.A.R.T. test: possibility to create multiple schedules (e.g. Quick daily, Extended weekly)
2. iTunes server to do home sharing, if at all possible (not proprietary technology or legal issues with Apple?). Net result would be the ability to see&share all media + playlists categorised by media kind (movie, tv show, music, audiobook etc) in NAS share.
3. Possibility to rename NAS volume(s) (just can't stand the "Volume_1")
4. Possibility to format single drive as RAID1. How else would it be possible to migrate Standard setup to RAID1 w/o data loss?
Perhaps after formatting RAID1 with single drive system could be in the state of one faulty drive?
5. Make the NAS more Mac OS X friendly. OS X might discover and mount the NAS as AFP share, instead of a SMB share as it does now. This might be due to wrong advertisement of _afpovertcp/_adisk services in Bonjour. For example the current beta firmware advertises some services on Bonjour completely wrong. As a reference, I've included Airport Extreme's service announcements for comparison. I assume the Airport advertises it's services over Bonjour correctly, as it performs flawlessly in concert with OS X:
(as seen through Bonjour Browser)

6. DLNA server to support more video formats (was already mentioned in conjunction with SONY TV-s), with transcoding, if possible. Although Sony BRAVIA DLNA is supposed to support MPEG-2 and AVCHD (H.264), the DNS-325 currently serves only MPEG-2 files in MPEG-PS container (.mpg, .mpeg) over DLNA. .mp4, .m4v and .m2ts files are simply ignored.
7. Add IPv6 support.
