It was in back 2007 when some folks from Google presented a very interesting paper on the 5th USENIX Conference on File and Storage Technologies (FAST’07). They looked into more the 100,000 disks over a period of about nine months. From its main findings the following points are particularly interesting:
- Only 44% of the failed drives showed relevant information in the SMART data
- Disk activity has no big impact
- Neither does temperature
I was quite astonished! If you are interested, please go ahead and read the full paper here.
