Disk swapping refers to the practice of inserting and removing, or swapping, floppy disks in a floppy disk drive-based computer system. In the early days of personal computers, before hard drives became commonplace, most fully outfitted computer systems had two floppy drives (addressed as A: and B: on MS-DOS, [1] and also on CP/M – other systems had different conventions).
However, it is common for mid to high-end servers and mainframes to feature hot-swappable capability for hardware components, such as CPU, memory, PCIe, SATA and SAS drives. An example of hot swapping is the express ability to pull a Universal Serial Bus (USB) peripheral device, such as a thumb drive, external hard disk drive (HDD), mouse ...
In data storage, disk mirroring is the replication of logical disk volumes onto separate physical hard disks in real time to ensure continuous availability. It is most commonly used in RAID 1 . A mirrored volume is a complete logical representation of separate volume copies.

In computer operating systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary storage [a] for use in main memory. [1] In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
Small Computer System Interface (SCSI, / ˈ s k ʌ z i / SKUZ-ee) [2] is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives.
The information is sent from the computer processor to the BIOS into a chip controlling the data transfer. This is then sent out to the hard drive via a multi-wire connector. Once the data is received onto the circuit board of the drive, they are translated and compressed into a format that the individual drive can use to store onto the disk ...
UltraBay Slim with DVD drive. UltraBay is originally IBM's name for the swappable drive bay in the ThinkPad range of laptop computers. When the ThinkPad product line was sold to Lenovo, the concept and the name stayed. It is also used in some of Lenovo's own IdeaPad Y Series laptops.
