Greg:
As a practical matter it makes no difference, performance-wise, whether the
WD drive supports the ATA 100 or the ATA 133 standard, The data transfer
rates that the PATA drives can achieve fall well below either standard. In
short, you'll see absolutely no difference in the performance between PATA
drives meeting either one of those standards that's due to the ATA
interface. It's conceivable that this might be an issue with the new
generation of high-rpm-speed, e.g., 10,000 rpm, SATA drives.
As to the other issue Peter raises with respect to your HP computer's
motherboard's BIOS supporting large-capacity disks, i.e., disks whose
capacity is > 137 GB, you can be sure that since that system's processor is
a 2.53 GHz one, it's a certainty there will be no problem in that area. I
assume your XP installation contains SP1 and/or SP2, since that will be a
requirement for the system to recognize the full capacity of the drive.
So go ahead and purchase that WD drive if it meets your other requirement as
to capacity.
