I am familiar with a storage company who has thousands of these exact
drives, all in JBODs and RAID arrays. They are pushed hard, daily. Other than standard drive failures as would be expected with any service like
this, there is no issue.

Same here, although not quite as much. I have about 250 drives (both EARS and EADS) across a range of servers and situations (some in London data-centers, others in office-based servers - and these in the office have regularly seen temperatures of 45oC in the room recently after I had issues with the AC units on the roof). Plus, the data-center machines are reading/writing at least three to five megabytes per second as a base-line minimum for much of their life.

My rate of loss is about a drive a month (maybe two or three drives if it's a bad month), but only around 8% a year. Even then, a drive with me will normally fail after either three weeks or three years. On the whole they're stable and have not caused me any great concern.

Considering temperatures alone, I've had more problems with Samsung drives than WD's Green range.
