WD Green 2TB, 64mb vs older 32mb

I was comparing the 32mb

vs the 64mb

Correct me if I'm wrong, but the 64mb uses 4k sectors and the 32mb uses 512b.

It's going in a Win 7 machine. Is there a reason to prefer one over the other? I didn't think the cache really made that much of a difference, and didn't know if the new 4k tech was better to avoid at the moment. Just wondering which to get. Just using it for storage. Thanks for any info!

You're correct about the 4K sectors on the WD20EARS and not the WD20EADS.

According to Western Digital's specification sheeet:
...both drives have the same sustained transfer rate and reliability rating, so I don't see any particular reason to choose one over another.
