Here are all the models currently in the database for this WD drive family. Entries are sorted into sections based on platter density.

Some tips:

Drives using odd sizes are sorted into whatever size category that's closest. For example, drives using 150GB platters are sorted into the 160GB/platter section, and drives using 200GB platters are sorted into the 250GB/platter section.
The total capacity of the drive is shown beside each drive model.
A platter-head ratio is shown next to the total capacity tag in brackets. For example, a drive with a (1/2) ratio has one disk and two read/write heads. Drives that leave some amount of their platters unused in order to fit into a certain capacity (such as a 320GB drive based on a 500GB platter and two heads, which would have ~180GB space unusable) are marked as [short-stroked] next to the platter-head ratio accordingly.
Any special features (increased rotational speed, interface types, unusual platter designs and stuff like that) are noted where necessary.

WD6401AALS-00J7B1 640GB (3/6 [short-stroked])*
*Note: Seems like a very early batch.
