Advice on storage purchase

Hi, quite a few of you seem to really know your computer hardware stuff, so I though I might as well ask here as well.

I need storage.  I have a small (8 stations, 2 switches, 1 router) home network that includes my Xbox 360 and 2 TiVos.  We have a new HD video camera, around 120GB of music, and about 180GB of porn.  I am looking to add between 1-2TB of storage to the network, and I want to run it mirrored.

I was thinking I would go with the Buffalo Terastation 1.6 or 2TB, but have not been keeping up on these for a while.  A year ago when I spent a week researching, the Terastation 1TB was the top dog.  Are these still win?  Or have they been surpassed?

Good deals on filing cabinets at staples.

Do you want NAS or internal?

Sorry, NAS.

Outside of building your own, you're probably best to look at a QNAP NAS. They are generally very feature-rich and have had fairly solid reviews for the majority of their products. While I haven't seen all of their products, they generally come without hard drives, so I'd end up pairing them with the Samsung HD103UJ.

If I ever move to a HTN and NAS-type solution for it, I'd probably go with QNAP.
