Detailed explanation-1: -Electrical storage: Solid State Storage Devices (SSD) Very compact in size and therefore very portable. High speed of data transfer and low power consumption. Considerably more expensive per unit than magnetic storage. More vulnerable to abrupt power loss and electro-magnetic fields.
Detailed explanation-2: -In addition, SSDs do not break as fast as magnetic drives due to the fact that there are no moving parts getting worn down. This keeps their heat transfer down, however, at this time, they are considerably more expensive than magnetic drives.
Detailed explanation-3: -Solid state devices are fast compared to magnetic and optical devices. They cannot hold as much data other devices. Solid state hard drives are more expensive that magnetic hard drives.
Detailed explanation-4: -It connects storage to the network using a network fabric. It gives block access to data. It provides dedicated file storage with its own file system. It’s preferred for structured data. It uses protocols such as iSCSI or Fibre Channel. 26-Nov-2019
