Cheapest 2 TB hard drives by Price per TB

2 TB is a common size for a laptop backup, a second drive or a small NAS. It is large enough for a sizeable photo library or media collection. Its price per TB is about the same as 1 TB and well above the larger sizes, so it pays to compare it with 4 TB and up. This page ranks the 2 TB hard drives we track by price per TB.

How to choose 2 TB hard drives

What to look for

Price per TB: compare 2 TB with 4 TB, because the larger drive can cost only slightly more in total.
Form factor: 2 TB comes in both 2.5-inch laptop and 3.5-inch desktop forms.
Recording method: some 2 TB drives use SMR, which can slow down on long writes. Check the model.
Interface: internal drives use SATA, and external drives use USB.
Warranty: consumer drives are covered for a shorter period than NAS lines.

Best for

Laptop backups, a second desktop drive and small media libraries.

Skip it if

You want the lowest price per TB, since larger sizes usually beat 2 TB.
