Salvestusandmekandjaid, also known as storage media, are physical devices used to store digital information. These media have evolved significantly over time, with each generation offering improvements in capacity, speed, and durability. Early forms of storage included punched cards and paper tape, which were largely mechanical and had very limited storage capacity. Magnetic storage, such as magnetic tape and floppy disks, revolutionized data storage by enabling magnetic patterns to represent bits of information. These were later supplemented and eventually superseded by hard disk drives (HDDs), which use spinning magnetic platters to store vast amounts of data.

Optical media, like CDs, DVDs, and Blu-ray discs, utilize lasers to read and write data to a disc's surface. While once popular for distributing software and media, their popularity has waned with the rise of faster and more convenient alternatives. Solid-state drives (SSDs) represent a significant leap forward, using flash memory with no moving parts. This results in much faster access times and greater resistance to physical shock compared to HDDs. Cloud storage, while not a physical device in the traditional sense, relies on vast arrays of physical storage hardware managed by service providers, offering a scalable and accessible way to store data remotely. The choice of storage media depends on factors such as cost, required capacity, access speed, and portability.
