External Devices

The LinkStation Pro Duo’s expandability options are limited to one USB port which doesn’t even support USB hubs. So, you can connect but one device to it. It can be an external storage device, an UPS or a printer.

The NAS can work with only one partition of external disks, formatted in FAT32, EXT2/3, XFS, HFS+ or NTFS. The latter two file systems are supported in read-only mode. The connected disk will be identified in the system as “usbdisk1”. The administrator can change access rights for it. The rest of the NAS resources become unavailable during the mounting of an external disk.

The NAS’s Function button can be used to quickly copy data from an external disk to a predefined folder on the NAS. When pressed for a long time, the button turns the connected external disk off safely.

The list of compatible UPSes is short and limited to products from APC and Omron. You may want to check out the list before purchasing an UPS for this NAS. If you've got multiple NASes on your network, you can set them up to share a single UPS.

You can also connect a printer to the NAS’s USB port. There are some limitations to this feature: you can’t view the printer's status and you can only use the printing module of an all-in-one.

The NAS’s printing functionality can be somewhat enhanced by using the Network-USB Server service we will discuss later on.

System Settings

The LinkStation Pro Duo lacks a special status page but its basic information can always be viewed in the left column. There is no way to check out the temperature or the SMART data of the HDDs. There is no event log, even. That’s not good, especially as the NAS is actually able to report HDD or fan-related problems by sending email notifications (you need to enter SMTP settings and a list of recipient addresses for that).

The integrated clock can be updated via the Internet. The NAS can automatically check for and install firmware updates. You can do this with an external program, too. There is no opportunity to save/restore the NAS's settings but you can reset them in two ways: with or without deleting user data. You can reset the NAS without deleting data by keeping the Function button pressed while starting the NAS up. You can prevent the admin password from being reset during these procedures.

The power management options differ from what we've seen with other NASes. There is Auto mode you can enable with the switch on the case of the NAS. When in this mode, the NAS will be automatically turning on and off depending on the availability of active PCs with NAS Navigator2 on the LAN. The NAS’s HDDs cannot be turned off but you can schedule the NAS’s operation using three on/off timers for each day of the week with 15-minute precision.

The admin can reboot the NAS but not shut it down from the web-interface. WoL is not supported by this model.
