Best shuckable drives by capacity

Updated June 2026

Jump to the capacity you want — each section ranks the available WD Elements, WD My Book and Seagate Expansion drives by live $/TB. Lower (greener) is the better deal.

Which capacity should you buy?

The short version: the 14–18 TB band usually wins on dollars per terabyte, smaller drives risk SMR, and the largest drives cost a premium until they go on sale. Use the live tables below to compare what each capacity actually costs today, then read the $/TB buying guide for what counts as a good price.

Best 24TB shuckable drive

Capacity FAQ

Which capacity is the best value for shucking?

Historically the 14–18 TB band offers the best dollars per terabyte on sale, with the sweet spot drifting upward as larger drives mature. Smaller drives lose to SMR and thin margins; the very largest carry a per-TB premium. Always compare the live $/TB before buying.

What is the cheapest external hard drive per TB right now?

It changes daily. The tables on this page are live and ranked by $/TB, so the cheapest current option is whichever sits highest (greenest) in each capacity section.

Are bigger drives always cheaper per TB?

Not always. Per-TB cost tends to be lowest in the mid-range (14–18 TB) and rises again at the very largest capacities, which command a premium until they go on sale.
