Yes as long as it is a 2.5" SATA hard drive.

By the way F.Y.I found out tonight from dell support tech replacing my video card,there is a 1 tera byte drive out now for laptops.

No, it won't.  The VelociRaptor is a 2.5" drive in a large heatsink that's for desktop use.  Not only will removing the drive from the heat sled violate the warranty on the drive, but the drive is sized such that it won't fit into a notebook computer.
