How to Pick the Right Drive Capacity for Your Use Case
If the MHU2100AT is going into a RAID array, choose RAID 6 over RAID 5 for any capacity tier built from drives larger than 4 TB. The probability of a second drive failing during rebuild from a 6+ TB rebuild window is high enough that single-parity is no longer responsible. For all-flash arrays, RAID 10 still wins on write-amplification-sensitive workloads (OLTP databases, VDI write-cache).
Drive Health Monitoring: SMART, Workload Rating, and Predictive Failure
Once the MHU2100AT is in production, the single most impactful operational practice is SMART monitoring tied to your existing alerting stack. SMART attributes 187 (reported uncorrectable errors), 197 (current pending sector count), and 198 (offline uncorrectable sector count) are the leading indicators of impending drive failure. Alert on non-zero values, not just on absolute thresholds; once these attributes leave zero, the drive has typically 30-90 days of useful life remaining.
