A RDX (removable disk exchange) is a data backup system that uses a removable disk.
A RDX combines the advantages of both tape and disk formats.
A RDX cartridges are compact and lightweight, yet robust and resistant to physical shock.
In addition, RDX cartridges can be inserted into a dedicated drive and connected to a PC with a USB cable to transfer data in a manner similar to that of floppy disks.
Furthermore, RDX can be carried offline or stored externally to protect important data from computer virus attacks.
The primary use of RDXs is for system and data backup in small and medium-sized businesses and SOHOs (small office, home office).
Large companies have many engineers with specialized knowledge and can handle difficult backups of systems and data using specialized tapes.
However, many small and medium-sized companies and sole proprietorships do not have engineers with specialized knowledge.
RDXs are relatively easy to handle, so even those without specialized knowledge can back up important data to a sturdy RDXs cartridge.
There are several ways to back up computer data, broadly categorized as tape-based and disk-based.
The advantages of tape-based backup are the robustness of the cartridge and its low cost. On the other hand, the disadvantages are that it can only be accessed sequentially (only desired data cannot be retrieved), data transfer is slow, and transferring data from tape to computer is complicated.
Disk-type tapes have the advantages of random access (only the desired data can be retrieved), high data transfer speed, and easy transfer procedures. On the other hand, it has the disadvantage of being vulnerable to shocks.
RDXs backup compensates for the disadvantages of tape and disk backup.
RDXs cartridges contain a small hard disk drive (HDD), which is protected from shocks by covering the vulnerable HDD with a shock-absorbing material.
RDXs can be used just like an ordinary external HDD, thus compensating for the shock vulnerability of a disk-type HDD while taking advantage of the HDD's strengths.
