Ranked by measured failure rate (Backblaze AFR). $/TB shows once live prices are wired.
Every drive here is a CMR (RAID-safe) 14TB model in current production. For a NAS or RAID array, pick the lowest failure rate you can afford; enterprise drives (Exos, Ultrastar, MG) trade some noise and power draw for the longest workload ratings. See how to choose a NAS drive for the full rundown.
