My old one crashed. Can't believe it. Would this be an acceptable replacement drive? http://eshop.macsales.com/Catalog_It...m=TOSMK1032GAX

or this one?

Help! Will the 16mb cache be that much of a benefit? I will be doing some graphics work, and some audio recording, but nothing heavy.

I have a Powerbook 12" with 1ghz and 512 of RAM.
