Cheapest 2.5" laptop hard drives by Price per TB

2.5-inch internal hard drives fit laptops, mini PCs, some game consoles and small enclosures. They draw little power, run quietly and are physically small, but capacities are far lower than 3.5-inch drives and the price per TB is higher. This page ranks every 2.5-inch internal hard drive we track by price per TB.

How to choose 2.5" laptop hard drives

What to look for

Thickness: 2.5-inch drives come in 7 mm and 9.5 mm or thicker versions. Check your laptop's bay before you buy.
Capacity: most are 1 to 5 TB, and bigger sizes are usually thicker.
Recording method: some large 2.5-inch drives use SMR, which can slow down on long writes. Check the model.
SSD alternative: a SATA SSD fits the same bay and is faster and more shock-resistant, though it costs more per TB.
Interface: SATA is standard, and older laptops may need a different adapter.

Best for

Laptops and small PCs that still use a 2.5-inch bay and need cheap extra space.

Skip it if

You want the lowest price per TB or the best speed. A 3.5-inch drive or an SSD does better.
