Notebook Hard Drive Question

[ilikecake]

I was thinking of upgrading the hard drive on my laptop from this

Toshiba MK4026GAX (40gb, 16mb cache) (http://www.newegg.com/Product/Product.asp?Item=N82E16822149015R)

to this

SAMSUNG HM120JC (120gb, 8mb cache) (http://www.newegg.com/Product/Product.asp?Item=N82E16822152032)

The Toshiba is the one that came with my dell. While the main reason I am upgrading is to get more space to store things, I was a little worried about the decrease in cache size. Is the smaller cache going to mean a slower drive? Will it be offset by the higher data density on the Samsung?

You shouldn't be able to notice a difference between them, but i am suprised that a 40GB hard drive came with a 16MB cache normally they use smaller ones on smaller hard drives.
