WD Purple storage hard drives and microSD cards have a much higher workload rate than their consumer branded counterparts. For example, the average desktop or laptop hard drive has a workload rate of about 55TB/year (assuming it's being used about 40hrs per week). On the other hand, WD Purple surveillance drives have a workload rate of 180TB/year, based on security recorders that operate 24/7. Likewise, the expected life of a Purple microSD card is much longer as well. For example, the 256GB microSD card will typically last around 100 months, compared to around 40 months. This higher workload rate greatly increases the reliability of the hard drive, so that there is a much lower risk of hard drive failure or data loss.
