This is a 9.5mm drive and will fit any Notebook with a SATA drive.

Where as the 750 and 1000GB drives are 12.5mm high so be wary as these won't fit most Notebooks

My self not really tempted to upgrade to one of these from my current 320GB drive, would prefer 1TB+

At 5400RPM and only 8MB cache this drive won't set any benchmark record, except the largest volume 9.5mm drive out today.

In NZ retailing for NZ$262 (~US$189)

For detailed specs head on over here
