What home file storage system are you using?

Over the years, like many of you I suspect, I've moved from one PC to another, and ended up with files scattered across many PCs and external hard drives.

A lot of the files are video - sports videos I've shot myself, or tv programmes I've recorded for posterity. And I have the usual work and personal files and lots of photos.

I've been wondering for a while what the best answer is for home file storage. I can't be alone here. I have looked into it, and there is a lot of choice, but no one answer stands out for me.

It needs to be simple and fast - but I don't really want to build a server in my airing cupboard. It should create backup files eg RAID technology. Ideally it needs to be scalable too - my files are growing over time.

Your thoughts and experiences are most welcome.
