14-20TB drives are the workhorses of enterprise storage arrays. A single 4U JBOD with 60 x 20TB delivers over 1PB of raw storage.
WD Ultrastar DC HC550 (18TB) and HC560 (20TB) use ePMR technology - a CMR variant that is fully RAID compatible despite the different recording method.
Large-capacity nearline drives are ideal for AI training data lakes where sequential read throughput matters more than random IOPS.
$/TB at these capacities has been declining steadily. Wait for quarterly promotions if not urgent - prices can swing 15-20% on enterprise bulk.
16TB SATA drives are excellent for high-density RAID 6 arrays. A 12-bay NAS with 16TB drives in RAID 6 yields 160TB usable storage.
Seagate Exos X18/X20, WD Ultrastar HC550/HC560, and MDD Enterprise are the main options. WD drives at 18TB+ use ePMR technology.
At 16TB, both new and refurbished options offer good value. New MDD drives with 5-year warranties are often priced close to refurbished brand-name units. Renewed Exos and Ultrastar drives are reliable choices for secondary storage.
