Jack’s organization recently received a shipment of SSDs and has begun to deploy them. What information would best help Jack assess the useful life of the devices?

Jack should use the manufacturer’s published mean time between failures (MTBF), which is a measure of the reliability of a system. It is the expected amount of time that will elapse between system failures. While organizations typically replace devices well before their MTBF ratings, knowing how long the devices should last on average can be useful in long- lived applications and for budgetary planning. A recovery time objective, or RTO, is set by organizations to describe how long restoring systems or services to normal function after a disruption can take. Mean time to repair, or MTTR, is the average time it takes to repair a system or device. A recovery point objective, or RPO, describes how much data can be lost in the event of an outage or issue.
