At first I thought it was basically a 32mb cache vs. an extra 100gb, but also heard that even though cache doesn't matter that much that the 32mb ones are newer and better anyway because they have dual processors or something. Does anyone know more about this? Which drive would you go for?
 
In fact, the WD7500AAKS’ HD Tach average read and write times (82.5MBps and 76.1MBps, respectively)
Only its random access time, 13.6ms, fell short of eclipsing the Raptor, which posted 8.1ms.

I own 1 640gb Black in my HTPC for quick boot time and game play...

and i own 5 WD GP drives, 4 750s and 1 500 for storage in my WHS...

which is limited to gigabit connection for speed of transfer, so the blacks would not get used to their potential


i think only you can really determine if you "need the extra 100gb of storage or do you need the 10+ mb/s transfer speeds"
