Cheapest NAS hard drives by Price per TB

NAS hard drives are built to run around the clock in a network storage box, often in a RAID group with several other drives. Lines such as IronWolf, IronWolf Pro and WD Red Plus and Red Pro are tuned for the vibration of neighboring drives, constant operation and longer warranties. Their price per TB is in the same range as other internal drives (see the comparison table below), so the main question is whether you need that workload rating.

Price charts

Value map: capacity against price

Each dot is one listing; 5 larger than 25 TB or priced above $100/TB are off the chart. Among drives at or above the median capacity (10 TB), the cheapest is MDD (MD14TSATA25672NAS) 14TB 7200 RPM 256MB Cache SATA 6.0Gb/s 3.5'' Internal... at $25/TB.

Price per TB by capacity

20 TB drives have the lowest median price per TB here ($33, from 17 listings). Capacities with fewer than 3 listings are left out.

How prices are spread

Half of the 123 listings cost between $33 and $57 per TB; the median is $46. A listing in the left-hand bars is cheap for this category.

How to choose NAS hard drives

What to look for

Recording method: for RAID and ZFS, look for CMR. Some SMR drives have caused long rebuilds and write stalls in NAS arrays, so confirm the model before you buy.
Bay count rating: entry NAS lines are rated for fewer bays, and Pro or enterprise lines are rated for larger arrays.
Workload and warranty: NAS lines usually carry a longer warranty and a higher workload rating than desktop drives. Check the exact numbers on the manufacturer's page.
Spin speed and noise: 5400 RPM class drives run quieter and cooler, and 7200 RPM drives respond faster. For a home NAS the quieter option is often enough.
Compatibility: check your NAS maker's compatibility list for the model.

Best for

Home and small-office NAS boxes, media servers and any always-on storage with two or more drives.

Skip it if

You want a single drive for occasional backups, where a cheaper desktop or external drive does the job.

Frequently asked questions

Can I use a desktop drive in a NAS?

It works for a single-drive setup, but NAS lines are designed for the vibration and constant use of a multi-bay box, so they are the safer choice for RAID.

Is CMR required for a NAS?

It is the safer option, particularly for RAID and ZFS, because SMR drives can slow down badly during rebuilds. Only some titles state the recording method, so read the datasheet.

What capacity should I buy for a NAS?

Compare the price per TB across sizes in the table, because the best value is often a mid-to-large drive rather than the biggest. Capacity mix and renewed listings change the median, so compare drives of the same size.

How much do NAS hard drives cost per TB?

Across 123 listings, the middle 80% range from about $30 to $68 per TB, with a median of $46. That is 8% below the all-HDD median of $50 per TB. Prices change often, so check the current price on Amazon before you buy.

What is the cheapest of the NAS hard drives per TB right now?

At the last update it is MDD (MD14TSATA25672NAS) 14TB 7200 RPM 256MB Cache SATA 6.0Gb/s 3.5'' Internal..., at $25 per TB. The cheapest listing is not always the best buy, so compare warranty, speed and reviews.
