This might be anecdotal but external WD (MyLife) drives are usually from the Green series and I had 2 different ones fail on me after about 1 year of use. Same happened to 2 friends of mine. I blamed it on the constant head parking (it went idle after 10 minutes of unuse).

I have 4 WD greens, one from an external enclosure the others being internal drivers, the first being maybe 3 years old now, all still going fine, also anecdotal
