What to Check Before Buying a 4TB Hard Drive
Check CMR or SMR for the exact model. For a NAS or sustained writes, start with your enclosure's compatibility list and workload requirements.
A manufacturer's specification describes an eligible new drive. OEM, bulk and renewed offers may have different seller or manufacturer coverage.
Confirm SATA versus SAS, drive dimensions, supported bays and the model-specific workload rating before buying.
Account for formatting, redundancy and free space. A mirror uses two drives to provide approximately one drive's capacity; it does not replace an independent backup.
