OK, so I just bought a "portable" notebook (VAIO TT series) -- for work / travel. Its nice and light, not powerful (VISTA Business, 1.2GHz, Core 2 Duo, 3GB RAM, 120GB Hard Drive - 100GB "usable") -- at any rate, its 1.3kg and very portable. My question is with regards to partitioning benefits. Obviously, if I had a computer with, say, 300GB+, I'd definitely partition it, but with roughly 100GB to work with, is it worth all of the trouble? If I did it, I'd go with prolly a 60/40 split giving the C:/ drive 60GB (and most of the apps / heavy programs) and a D:/ drive for files... But the question stands, with just 100GB to work with is it worth the trouble? will i see a noticeable performance improvement? Thanks
