As stated in the subject I am curious to know how many RPMs my “WD-My Passport” HD has.
Product in question : http://www.amazon.com/Passport-Portable-External-Storage-WDBBEP0010BRD-NESN/dp/B007FQNLOY/ref=sr_1_11?ie=UTF8&qid=1380106561&sr=8-11&keywords=my+passport
Furthermore, what would be the advantages of purchasing a WD MyBook? What distinguishes it from the My Passport?
