I currently have my Windows XP Home SP3 on a Western Digital 2tb

StatBar usually says that the CPU is staying well below 100 percent.

Would replacing this drive with a Hitachi 2TB 7200RPM SATA hard
drive speed my system significantly? Thank you in advance for all
replies.

I doubt it. Spend the money on more RAM instead. Even under
the best circumstances going from 5400rpm to 7200rpm
gives you less than a 30% speedup, as data-densities on 5400rpm
drives are typically higher.

It would not be much money. I plan to buy a DVR that would need a
hard drive. I thought I would buy a 7200 rpm drive, put it into the
computer and then use the old drive in the DVR. The real cost is
the difference between the price of a 2tb 5400 rpm drive and a 7200
rpm drive.

Ah, then go for it. Just don't expect much speed gain.

There are two things that my computer does slowly:

1. Search for and delete duplicate picture files with CloneSpy
version 2.6. I have over 320,000 picture files that it has to
compare.

2. Do a global search with Agent version 5.0. Agent 5.0 uses one
data file and one index file for each newsgroup. It compresses the
data files. Some of the data files are about eight gigabytes.

Well, in that case you may see the 30%. But better look at the
transfer rates of the new disk, 7200rpm drives can be as slow
as 5400rpm ones for these applications, but they can also
be faster. For Hitachi, you will probably get faster ;-)
