About the 18TB external hard drive
Listings for 18TB external 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.
- External drives are often cheaper per TB than the same drive sold bare, which is why people "shuck" them: take the drive out of the enclosure and use it internally. That can void the warranty.
- Some shucked drives need the 3.3V pin taped over before they spin up on certain power supplies.

Questions
- What is a good price for an 18TB external hard drive?
- Based on 97 price points from 17 listings tracked since Sep 2026, the typical price is about $470, and most listings fall between $400 and $500. Anything well under the typical price is a good deal, as long as the condition and seller feedback check out.
- What is the lowest price you have tracked for an 18TB external hard drive?
- The lowest we have logged is $329 on Sep 5, 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.
