Introduction to Storage Technology: Primary Storage, Secondary Storage, NAS, and SAN

Storage technology is where data is stored in digital format for retrieval at a later point in time.
Storage devices are computing hardware used for storing, porting, and extracting data files or objects.
Primary storage devices are internal to a computer or server, hold data temporarily, and have limited capacity.
Secondary storage devices are larger in capacity, can be internal or external, and can hold data permanently or temporarily.
The measure of storage capacity is in bits and bytes, with 1 GB being equivalent to 1024 kilobytes and 1 PB being equivalent to 1024 terabytes.
The exponential growth of data led to the need for storage technologies such as NAS and SAN.
NAS devices connect storage to a network, where they are accessed through file shares by multiple systems with permissions.
SAN is a dedicated network that allows storage to be shared between multiple servers, and data is stored in volumes or blocks.
SAN devices provide continuous and fast access to large amounts of data, and communication and data transfer mechanism is through storage fabric.
SAN uses separate networks and is generally not accessible by other devices in the local area network.
NAS is optimized for file serving, whereas SAN is a block-level device that provides greater flexibility and additional functionalities.
Despite the differences between NAS and SAN, they blend together well, with many NAS providing support for iSCSI and many SAN providing support for SMB and NAS file systems.
