Storage systems refer to technological solutions used to store, manage and access digital data. They usually consist of hardware, software and network components. Basic storage systems include hard disks (HDD), solid-state drives (SSD), magnetic tapes, optical disks, and network-attached storage (NAS) and storage area network (SAN) systems. Modern storage solutions are designed to prevent data loss, provide high access speeds, and effectively manage large amounts of data. Cloud storage allows data to be stored on remote servers over the internet and offers access from anywhere. The selection of storage systems varies depending on the required storage capacity, access speed, security requirements, and cost factors.
