Find the Cheapest 12TB NAS Drive Today

Who a 12TB NAS drive suits

12TB is in the value sweet spot, the size most home and small-office NAS buyers should choose. It suits a 2-bay or 4-bay unit for a growing Plex library, photo archive and backups without overpaying for capacity you will not use for years.

12TB is a strong Plex size: a pair or a four-bay pool gives room for a real 1080p and 4K library with headroom to grow over a couple of years.

Where 12TB sits on the value curve

This is the cheapest part of the price-per-terabyte curve. 12TB drives typically give the best value per terabyte of any NAS-rated size, which is why 8TB to 12TB is the most common recommendation. You pay a little more in total than a small drive but far less per terabyte.

At 12TB the value picks are WD Red Plus, Seagate IronWolf and Toshiba N300, which trade the lead on price per terabyte. The live table is sorted so the cheapest per terabyte is at the top.
