D-Link has packed the 325 with lots of features missing from the earlier-generation 321 / 323 / 343. Here's a summary of the tricks it can do:
Volume Types, File Systems, Services
- Network file sharing via SMB/CIFS, NFS, AFP and WebDAV
- Oplock enable/disable per share
- Individual, JBOD, RAID 0, 1 volumes
- EXT3 file system
- FTP (and -SSL, -TLS) with FXP support, IP block list, bandwidth control (
no anonymous FTP)
- HTTP / HTTPs file and admin access
- ISO mounts
- Network Recycle bin support
- USB printer serving
D-Link told me anonymous FTP is supported and is set up in Network Shares. This is documented on Page 53 of the User Manual.
- User and Group quotas
- Scheduled and immediate networked backup to and from other D-Link NASes and rsync servers ("Remote Backups")
- Internal scheduled and immediate folder to folder backup ("Local Backup")
- Internal scheduled and immediate folder backup from only FTP or UNC share ("Local Backup")
- USB device pushbutton copy to NAS
- Apple Time Machine backup
- FarStone TotalRecovery Pro bundled client backup for Windows
- Media servers: UPnP AV / DLNA, iTunes
- PS3 and Xbox360 media access support
- FTP / HTTP single file download
- BitTorrent download witih schedule and bandwidth control
- Programmable idle drive spindown
- Scheduled shutdown
- Auto restart after power failure
- Link speed setting
- LLTD enable / disable
- Dynamic DNS support (dlinkddns.com,DynDNS.org [custom & free options], no-ip.DDNS)
- Email alerts w/ SMTP authentication
- SMS alerts
- Onscreen logs
- Syslog support
- Remote restart, reset to default, shutdown
- System temperature shutdown
- Schedulable S.M.A.R.T test
- On-demand volume error scan
As much as D-Link has expanded the 325's capabilities, there are a few things that you should know that it doesn't have:
- iSCSI support - The 325's volumes can't be used as iSCSI targets. There is also no ability to mount other iSCSI targets to expand storage
- No backup to USB drive - This is an odd exception, given the ability to run networked rsync backups and to copy from SMB shares and FTP servers to the 325's storage.
- Cloud backup option - This could be added via an Add On. But, for now, you can't back up to Amazon S3 or any other cloud storage provider.
- IPv6 - It's not a big deal to me, but the Network controls are strictly good ol' IPv4.
- NT Domain / Active Directories support - This is not a business-class NAS. So you can't authenticate users via either of Microsoft's widely-supported methods.
The admin interface is pretty slick and visually appealing. Figure 7 shows the My Favorites page that will greet you upon logging in via your choice of HTTP or secure HTTPs. I've customized this page a bit by drag and dropping icons from the Applications and Management sections.
I should note that Firefox threw an invalid certificate message a few times when I tried to log in using HTTPs. After I deleted the certificate and restarted the browser, I was able to successfully log in, however.

The Recent Activities section on the right shows the most recent log contents. Unfortunately, the log doesn't contain information about backup or any application activities. Perhaps this info is sent to the syslog stream that is also supported, but I didn't check.
Drive setup is guided by a wizard that you can see in the gallery. When creating a volume, you can reserve some of the available space for a second volume that will be set up as JBOD. The gallery also shows an assortment of other interesting admin pages.
Browsing through the admin interface kept revealing little surprises. Like per-share oplock enable / disable (enabled by default) and ISO mount support in the Network Shares section. It was also via the Network Shares Setup Wizard that I discovered the 325's WebDAV support. Both these are illustrated in the gallery.
The FTP server can have secure SSL / TLS connection enabled and bandwidth throttled. But you can't enable anonymous mode and a maximum of 10 user accounts are allowed. Check the gallery for a screenshot with more settings.
There are both UPnP / DLNA and iTunes servers. The only control for the former is a screen to add files and force a database refresh. The iTunes server controls include auto rescan time. I could not find hidden web interfaces for either of these servers. D-Link says the UPnP / DLNA server supports their Boxee Box, PS3 and Xbox 360. I didn't verify any of these.
Note that the 325 doesn't create any media folders by default. So it's up to you to organize your own media files.
