Storages are required to save the data. There are multiple types of storages

Local Storage 

1. External Hard Drive

These are hard drives similar to the type that is installed within a desktop computer or laptop computer. The difference being that they can be plugged in to the computer or removed and kept separate from the main computer

2. Solid State Drive (SSD)

Solid State Drives look and function similar to traditional mechanical/ magnetic hard drives but the similarities stop there. Internally, they are completely different. They have no moving parts or rotating platers. They rely solely on semiconductors and electronics for data storage making it a more reliable and robust than traditional magnetic. No moving parts also means that they use less power than traditional hard drives and are much faster too.

3. Network Attached Storage (NAS)

NAS are simply one or more regular IDE or SATA hard drives plugged in an array storage enclosure and connected to a network Router or Hub through a Ethernet port.  Some of these NAS enclosures  have ventilating fans to protect the hard drives from overheating.

4. Storage Area Network(SAN)

is a Computer network which provides access to consolidated, block-level data storage. SANs are primarily used to enhance accessibility of storage devices, such as disk arrays and tape libraries, to servers so that the devices appear to the operating system as locally-attached devices. A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN) by other devices, thereby preventing interference of LAN traffic in data transfer.
