WD HDD Model Number meanings

[HittingSmoke]

I found this about a year ago on google but for the life of me I cant find it again.

I want to the know the cryptic meanings behind those Western Digital model numbers. I know each 2 letter and/or number group represents a spec or feature. A while back I found a PDF on google that had a detailed which parts of the model number meant what but after hours of searching I cant find it again.

If anyone has a link to this please help me out.

You need to work on your googling skills. Type in "wd model numbering" and look what I found at the top: http://www.wdc.com/en/library/2579-001028.pdf
