2TB Hard Drives
The Seagate 2TB drives were also removed from service in 2015. While their cumulative failure rate was slightly high at 10.1%, they were removed from service because we only had 225 of those drives and it was easier to upgrade the Storage Pods to 4TB drives than to buy and stock the 2TB Seagate drives.

On the other hand, we still have over 4,500 HGST 2TB drives in operation. Their average age is nearly five years (58.6 months) and their cumulative failure rate is a meager 1.55%. At some point we will want to upgrade the 100 Storage Pods they occupy to 4TB or 6TB drives, but for now the 2TB HSGT drives are performing very well
