Well, I want to get a new hard disk and I'm thinking of 750GB/1TB. I already have 250 + 160GB 7200.10s. As there isn't enough space, I'll get a bigger one and will run all three. Should I just get a 1TB Seagate or since SSDs will dominate, make do with the current space and upgrade after a year or so? I will use it mainly to store video files.
