About the 20TB hard drive
Listings for 20TB 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 20.
- 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.

- What is the lowest price you have tracked for a 20TB hard drive?
- The lowest we have logged is $220 on Sep 29, 2026. Listings sold for parts, as-is or untested, and extreme outliers are left out so one odd listing doesn't set the record.
- Where do these prices come from?
- Every time the Disk & SSD Tracker refreshes (every few hours) it logs each matching listing (from eBay, Amazon and other stores, via PricePerGig) to this site's own price history database. This page summarizes that history. It's our own data, not copied from another site, and the listing itself is always the final word on price and condition.
