You can get hard drives up to 750gb now. That coupled with the new blu-ray writers should give you enough space, and still allow the option of backup to DVD.
Obviously that's the high (and expensive) end of the spectrum. You haven't said how much hard drive space you currently have. I do a fair bit of video stuff myself and my 80gb drive is capable of managing a couple of one hour productions (just). I've recently bought a new Western Digital 200gb drive for £48 just to give me a bit more breathing space.
Mine is IDE but if you do serious video editing you should consider SATA for its speed.
