I hate to be that guy to ask this, but why does it matter? There are only a few 2TB 7200RPM hard drives on the market (plus several with slower spindle speeds), and their performance is all but identical.
The Hitachi Deskstar HD32000 has 32MB of cache. The Seagate Barracuda XT ST32000641AS and Western Digital Caviar Black WD2001FASS both have 64MB of cache. Apple probably buys from whichever vendor quotes them the best price this month.

Thanks for your answer.
I am happy to hear that the performance are nearly identical (and I expect good)

Buying from multiple vendors also partially protects your products if one has a bad batch.
