Detailed explanation-1: -Optical discs are not vulnerable to data loss due to power failure like volatile memory, and they’re not as subject to wear as non-volatile memory (NVM) such as HDDs and flash SSDs. Optical discs are also much sturdier than magnetic tape, which is the leading archival storage medium.
Detailed explanation-2: -A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
Detailed explanation-3: -In the case of the computer, they are normally in-built and therefore are not portable. Some hard drives are reversible, so between machines, they provide easy portable storage. In general, they are efficient and stable, with easy access to stored data.
