Buy Hard Drive for Dell Inspiron 600M ATA100 or is ATA 133 OK to use?

I have a working Dell Inspiron 600M laptop with no Hard Drive.
I want to buy one & wonder if I have to stay with the original type drive:
ATA-100 IDE 44pin
or can I buy a Faster ATA-133 IDE drive (not sure what pins that has)?

Hi Jim,

You are absolutely safe to purchase an ATA133 drive to use with the slower controller in your laptop. Even though a drive supports newer and faster controller speeds (timing specs), they always support every preceding controller speed ever created.

Since the hard-disk is usually a bottleneck in a computer system, ensure that you purchase the fastest drive which you can: 5400 rpm (versus 4200 rpm) and 8 or 16 MB cache (as compared to less).
