Hey. I'm getting some storage for a scratch build I'm starting this week and I already have an SSD, but no HDD, so I was going to buy a 1TB one. I found two WD Drives at Amazon and one's $100 while the other's $75, but they don't seem to have any difference. They're both 1TB, have a 64MB cache, spin at 7200RPM, are a 3.5 inch form factor. Here are the links so you guys can have a look yourselves:

If you could tell me the difference between them apart from warranty, it would be greatly appreciated. Thanks!

There doesn't appear to be any difference in performance or capacity between those drives. Though I would lean towards the WD Black $25 is a small price to pay for an extra 3 years of warranty.

The Caviar Blue product line is designed for mainstream use.

The Caviar Black product line is designed for performance use.

The Caviar Black drives have faster response times and overall higher throughput than the Caviar Blue drives, which makes them more expensive.
