I am about to purchase a sager 4881 and I noticed I can upgrade from a 7200 RPM 60 gb hard drive to a 100 gb 5400 RPM drive for only $15. Is there really that much of a difference in performance. 40 extra gigs would be great what should I do?

depends on what u want more. the speed or the space. the speed difference is pretty noticeable in file transfers from what i've read.

I would get then larger capacity. The difference between the 5400rpm to the 7200rpm isn't as significant as the jump from 4200 to 5400 rpm.
The bigger drive is the better value in my opinion.

I would always, and i mean always pick speed over capacity. I mean think about it... 40 gig or even 80gig. It's only 2x difference and if you just use your space smart and keep large stuff of the HD (and most of us know, lesser space used - lower fragmentation and thus better performance).
Although the increase in overall performance is around... 25% or so, the access time and responsiveness is very noticable.
It's like ram... you'd have lower latency ram timings, b/c the responsiveness of the system is so much greater! If some of you disagree, all i have to say... you have to experience it.
Space dont' matter... speed matters!!!

People, start spreading this stuff around. All these people asking the same questions is annoying.

Think about it this way...size is upgradable (larger drive, external drive for storage etc.)

speed is not upgradable

so get the faster one now, and if u do need more space, just simply get a cheap desktop hard drive and pop in into and enclosure and boom u can have up to 300gigs of space and still not sacrifice the speed of ur original laptop. also, desktop hds are 7200rpm or more anyways, so its not like ur goin down in speed when doin this.

well the difference between those specific drives is pretty nil. The areal density of the 100GB nearly makes up for the speed of the 7k.

Areal density increases transfer rates (read/write), but those are sequential. Random transfer rates are still faster for 7,2k drives and the access times are still a lot faster for 7,200rpm as well.
