Currently I have the 40 GB Toshiba 5400rpm 16 MB cache drive I sold my stock 4200rpm drive in my R50e and for almost the same price got this one, it's been half a year now, but with the dual Fedora Core & Windows XP boot add to that my videos and media, I am pushing my available drive space to the max and I ATM have like 8 GB of free harddrive space, so as you can see I am looking forward for an 80 Gb harddrive as that will serve my needs for a while.
And since I am going to upgrade for size I might as well take the dive and go for an 80 Gb 7200 rpm drive as opposed to a 5400rpm drive the boot speed would be better and I would be at an advantage if I decided to do things like photo-editing or more intensive video-editing in the fututre, I know I would love to have a 7200rpm drive in my laptop, but if it wasn't the size upgrade I wouldn't have allowed myself to considre that upgrade.
