Hard Drive Finder

Three questions — how much capacity, what you can spend and how it connects — across 278 drives. Every result is placed against the median for its own class and capacity band.

Your requirements

How much capacity do you need?

This is the only specification here that changes what you pay per terabyte, and it changes it steeply — the largest drives cost roughly half per terabyte what the smallest do. Buying fewer, bigger drives is usually cheaper than buying more small ones.

What can you spend?

A ceiling, not a band — each option includes everything cheaper. Prices move daily, so these are tiers rather than amounts.

How does it connect?

An internal drive on SATA or SAS goes in a machine or a bay; a USB drive is an internal drive in an enclosure and is sold by the box as much as the platters.

How to read the results

A result is not a recommendation. A drive appears because its listing publishes the figures the comparison needs, and it is shown against the median for its own class so you can see where it sits rather than being told it is best.

Prices are shown as tiers rather than amounts, because the price on Amazon at the moment you buy is the only one that is true. The methodology page explains what is withheld and why.
