as above, is it do-able?
in the asus c90 to be more correct
yes. it is possible though not plausible.
Humungous drives are the rage today. I suppose there might be a maker of a 1/2 terabyte laptop hard disk drive that is internal. I haven't run across one myself though and I really see no reason to have one except to store movies.
There are plenty of these size drives that are external.
That's a lot of laptop.. 160GB is pretty huge for them too.. The future laptop will use more flash type of drive built in like you have with digital cameras but until larger sizes become above right now they're too small. I know 32GB SD/HC is coming out soon. But to have this buit-in which is alot quicker than any 7200Rpms or 10,000Rpms HDDs.
I've seen 320 gig 2.5" hardrives, but not too sure about 500. I don't see why it isn't possible though.
Tedster: If they make external ones of that size, why couldn't you just remove the casing and plop it into the laptop?
