Buffalo TeraStation Pro Duo WSS preview: NAS with Windows Storage Server

The Buffalo TeraStation 5200 is a small office NAS that we recently reviewed. We saw that it had a VGA port on the front, which isn't very useful for a NAS like the TeraStation 5200. It's a different matter with the TeraStation Pro Duo WSS, which looks like the identical twin of the 5200, but instead is equipped with Windows Storage Server 2008 R2 Workgroup Edition.

This is different to Windows Storage Server 2008 R2 Essentials, which is a version of Windows Home Server. This is the true Windows 2008 R2 Storage Server, without the Dashboard, but with all of the features you expect from Windows Storage Server 2008 R2. This Workgroup version of Windows 2008 R2 Storage Server can handle 50 simultaneous SMB connections. It also functions as an iSCSI target and initiator, which means you can use it both as an iSCSI client and server.

It has business features such as de-duplicating files (Windows Single Instance Storage), which prevents files from being saved twice and can free up a lot of space. It's also possible to create a distributed file system (DFS). Basically it's also a smart, compact file server on a Windows network, which you can set up as a back-up server as well. For that Buffalo has included back-up and replication software.

The TeraStation Pro Duo WSS has two hard drives, in our case two Seagate 2TB Barracuda Green ST2000DL001 disks. You can also buy it with two 1TB disks. Like its NAS devices, Buffalo always includes hard drives with its storage servers.

The disks are hidden behind a door that can be locked with a key. There you also find a VGA port, and on the front there is a display where you can see the status. The USB ports are on the back, where you can connect mouse and keyboard. You can read the rest of Buffalo TeraStation Pro Duo WSS preview on
