CMR (traditional magnetic recording) writing is non overlapping and has stable performance; SMR (Stacked Tile Magnetic Recording) has overlapping writing and large capacity, but slow random writing.
HDD Applicable Scenarios
Cold data storage, large capacity warehouse disk, NAS backup. Not suitable for system disks and scenarios with frequent writes.
Purchase suggestions
Select CMR enterprise grade hard drive for NAS; Select 7200 RPM CMR for desktop storage; Avoid pitfalls and use SMR tile stacking discs as the main focus.
