Western Digital Drives

Can someone explain to me the difference between

AAJS
AAKS
KS
YS

disk drives

Is the difference between the AAKS and the AAJS just the 8Mb Cache difference or am I missing something on the website

Also if on a RAID5 Media Storage am I really going to notice the difference.

AAJS - 2nd Gen 8MB Cache
AAKS - 2nd Gen 16MB Cache
KS - 1st Gen 16MB Cache
YS - RAID Edition

You are correct in the difference between the JS and KS. The JS are a fraction cheaper but I'd just go for the KS. If you're running 24/7 in RAID the YS is the better drive but the KS is best for performance unless you go for the new AYYS 750GB RAID Edition.
