Pros: Quite

Cons: Drive was slow, MBP Seemed to drop battery faster with this drive installed.

Overall Review: With regards to my Cons... Keep in mind that this drive completely died on me after 2 weeks of extreme light use, possibly 16 hours total and I seriously think that's pushing it. Even though the drive went down hill in a days period, it may have been a faulty drive from the get go which may account for the slight battery drainage and slow-poor performance. Not sure if I'll try another or go with a WD.
