Last year I upgraded the supplied 40 GB 4,200 RPM(Rotations per minute) hard drive on my Dell 700m notebook to a 100 GB 7200 RPM hard drive.
Being the early adopter that I am I paid dearly for it at the time ($220 or so) but it was the best upgrade that I made on my laptop.
The performance boost from the 7,200 RPM hard drive was much more noticeable than from more RAM or a faster processor.
After the upgrade windows booted up in literally half the time, and programs opened up without any delays (e.g. before the upgrade firefox used to take a fair amount of time to open up, afterwards it didn’t take any time at all!)
At any rate Dell is now selling the 160GB 7,200 RPM drive for just $129, which is an unbeatable price.
The drive is manufactured by Seagate. (You can tell that it’s a Seagate by clicking on the picture of the hard drive to enlarge the image!)
Even though the links say that it’s for a “Latitude D820″ this will work fine in any notebook that takes standard 2.5” SATA notebook hard drives.
This drive is available from Dell Home Outlet or Dell Small Business.
I would recommend buying from Dell Small Business, just in case Dell Home Outlet might send you a refurbished drive!
