The backup company’s latest hard drive report is mildly more amusing than usual, as their systems now include a significant number of enterprise drives. Unfortunately, it is still too early to comment on their failure rates, but some obvious benefits include faster data loading, even when certain power management features were engaged. Again, there are charts demonstrating how the usual Seagates, WDs, Toshibas, and HGSTs fared.

Backblaze has now recorded and saved daily hard drive statistics from the drives in our data centers for over 4 years. This data includes the SMART attributes reported by each drive, along with related information such as the drive serial number and failure status. As of March 31, 2017 we had 84,469 operational hard drives. Of that there were 1,800 boot drives and 82,669 data drives. For our review, we remove drive models of which we have less than 45 drives, leaving us to analyze 82,516 hard drives for this report. There are currently 17 different hard drives models, ranging in size from 3 to 8 TB in size. All of these models are 3آ½" drives.
