How much does operating temperature affect the failure rates of disk drives? Not much. The unlimited online backup service provided by Backblaze requires a lot of storage. In fact, we recently passed the 100PB mark in our data center. This means we use disk drives. A lot of disk drives. The Backblaze Storage Pod is designed to provide good air flow over the disk drives, so they don’t get too hot.
