Several disks (minimum 2) connected through a special controller or in the case of software implementation, connected through different IDE ports (loops). Information on the disks is duplicated and in case of failure of at least one of them The computer can continue to operate normally. A faulty disk can be replaced and the information on it can be recovered from other disks. There are different options, usually use mirroring (minimum 2 drives) when the information is on drives simply duplicated, or Raid level 5 when there are 3 or more drives. It is worth noting that a disk array can burn out entirely if there is a faulty source power supply, may be formatted by malware, information may be destroyed due to errors in programs, disks in drives can be demagnetized under the influence of various anomalous phenomena such as UFOs... therefore backup still necessary.
