About the 18TB hard drive

Listings for 18TB hard drives from the Disk & SSD Tracker, grouped by nominal size: new, used and recertified drives from every brand. Prices here are for the whole drive; the per-TB figure is the price divided by 18.

Used and recertified enterprise drives (Seagate Exos, WD Ultrastar, Toshiba MG) make up a lot of the cheapest listings. They can be good value, but check the warranty and ask for SMART power-on hours.
Some cheap listings are SAS drives, which need a SAS controller or HBA and won't plug into a normal SATA motherboard port.
Some smaller and consumer drives use SMR recording, which is slow to rebuild in ZFS and some RAID setups. NAS buyers should check before buying.
