at the time there were 32 file servers, each with a 60 disk array attached. Thats almost 2000 spinny disks.
At that scale we'd expect about one failing disk every two weeks+. We were covered by a 24/7/365 4 hour warranty. This means that a replacement disk will appear within 4 hours, anytime of the year.
From what I understand the old disks are taken back, examined, refurbished and sent out again. I've heard that its often head alignmet, and or track setup issues that cause the most problems.
But yeah, there is waste....
+in practice we had a lot more disks than this, as we needed fast online backup. so we'd normally have at least two failed disks a week.
