CMR Hard Drives: Cheapest by Price per TB

CMR (conventional magnetic recording) writes each track separately, while SMR (shingled magnetic recording) overlaps tracks to squeeze in more data. CMR drives keep consistent write speeds, which is why they are the safer choice for RAID, ZFS and NAS arrays. This page lists every hard drive whose title states CMR, ranked by price per TB.

How to choose CMR hard drives

What to look for

Stated in the title: this list only includes drives whose title says CMR. Many CMR drives do not say it in the title, so a missing model may still be CMR.
NAS and RAID: CMR is the safer match for arrays and ZFS, because SMR drives can slow down badly during rebuilds.
Model lines: NAS and enterprise lines such as WD Red Plus and Pro, IronWolf and Exos are generally CMR, but confirm the exact model on the manufacturer's page.
Capacity: CMR is common at large sizes, but not every title says so, so use the datasheet for the exact model.
Warranty: CMR drives in NAS and enterprise lines usually carry a longer warranty.

Best for

NAS, RAID, ZFS and anyone who writes large amounts of data regularly.

Skip it if

You only need a cheap backup drive that is written to occasionally, where SMR is acceptable.

Frequently asked questions

Is CMR better than SMR?

For sustained or random writes and arrays, yes. SMR is fine for archives and backups that are written once and read often.

How do I know if a drive is CMR?

Check the manufacturer's datasheet for the exact model number. Some manufacturers publish a list of which models are CMR and SMR.

How do CMR prices compare?

Here the median is $48 per TB, compared with $49 per TB across all internal drives.

How much do CMR hard drives cost per TB?

Across 80 listings, the middle 80% range from about $33 to $77 per TB, with a median of $48. That is 5% below the all-HDD median of $50 per TB. Prices change often, so check the current price on Amazon before you buy.
