Tape Drives and Tape Libraries are primarily used for backups and as the final stage of digital archiving.  Legacy Tape Drives and Tape Libraries

Flash storage is an electronic non-volatile computer storage medium that can be erased and reprogrammed. Flash delivers extreme performance to derive measurable economic value across the data architecture – servers, software, applications and storage.

A storage area network (SAN) is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to enhance storage devices, such as disk arrays and tape libraries, accessible to servers so that the devices appear like locally attached devices to the operating system. A SAN typically has its own network of storage devices that are generally not accessible through the local area network by other devices.

Network-attached storage (NAS) is a dedicated disk storage device that is set up with its own network, providing file-based data storage services to other devices on the network, allowing both application programming and files to be served faster because they are not competing for processor resources.

Unified Storage is a storage system that makes it possible to run and manage files and applications from a single device. Unified storage system consolidates file-based and block-based access in a single storage platform and supports fibre channel SAN, IP-based SAN (iSCSI), and NAS .
