Difference in WD5000KS, WD5000AAKB, WD5000AAKS

What are the differences in these 3 types of WD drives...I have been searching google and I have decided to just ask someone that knows.

5000KS is the old 500 GB, 16 mb cache, slower, sata drive
5000AAKS is the new 500 GB, 16 mb cache, bigger platter, faster, sata drive
5000AAKB is the same as the AAKS, except its an IDE drive
