Basically I want a high capacity hard drive which I can leave on my desk at home and put all the files I don't need everyday (video, music, pictures, etc...), whilst being able to take my laptop with me wherever I need to go.
I have been told my best bet would be to build one, but I don't really know where to start.
I've been looking on ebay and there are some cheap 250/320GB Seagate drives on there and I've been told they're fairly reliable. Also, with an ext.HD would I be able to put things straight onto it from a USB device? Or would I have to plug the lead into my laptop and select which hard drive I want it on? And would I be able to play files from the hard drive on my laptop without having to move them onto it's hard drive?
Another thing I've been hearing about is SATA. What's that? Is it possible to get a SATA > USB converter because I don't have a SATA port on my laptop.
