Backing storage media can be organized in increasing order of capacity as follows: floppy disks, CDs/DVDs, USB flash drives, external hard drives, and cloud storage. Floppy disks typically hold 1.44 MB, while CDs can store about 700 MB. USB flash drives generally offer capacities ranging from a few gigabytes to several terabytes, and external hard drives can reach capacities of up to 20 TB or more. Cloud storage solutions can provide virtually limitless storage, depending on the service and subscription plan.

Backing storage refers to non-volatile storage systems used to retain data permanently, such as hard drives, solid-state drives, and optical discs. It serves as a complement to primary storage (like RAM) by providing a larger capacity for data retention, even when the power is off. A media track, on the other hand, is a concentric circle on a storage medium, such as a hard disk or optical disc, where data is recorded and retrieved. Each track can hold a significant amount of information organized into sectors, which are the smallest units of storage on the medium.
Optical backing storage refers to data storage technology that uses optical discs, such as CDs, DVDs, and Blu-ray discs, to store and retrieve digital information. These discs are read and written using laser technology, allowing for high-capacity storage and durability. Optical backing storage is often used for archival purposes, software distribution, and media storage due to its resistance to electromagnetic interference and long shelf life. However, it is generally slower than other storage methods like hard drives or solid-state drives.

Solid state storage regards media and devices that are not moving as in conventional hard disks. Solid states devices include SSDs and flash memory modules.

No, some cards offer higher storage capacity and more rapid transfer rates.

All storage media have their limits. As far as how much information can be stored on a CD, I can't give you an absolute figure. They do come in different storage capacity sized though.
Do you want compressed or uncompressed video? A DVD can store a compressed full-length movie, but you would have to go to Blu Ray to store an uncompressed feature length film.
An autochanger increases the overall storage capacity of a backup solution by allowing multiple storage media, such as tapes or disks, to be loaded and accessed automatically. This means that instead of relying on a single tape or disk for backups, the autochanger can switch between numerous media, effectively expanding the total amount of data that can be stored. Additionally, it streamlines the backup process by automating the retrieval and storage of data, reducing manual intervention and potential errors. This functionality enables organizations to manage larger datasets efficiently while optimizing their backup resources.
