What Is Network Attached Storage (NAS) Device?

For storing a document or file there are many hardware and software available presently. These are like CD’s, floppy, pen drive, memory card, internal hard disk, external hard disk, etc. Apart from these devices, one more extra network storage device is available which is called as network attached storage (NAS). This helps in reducing the unwanted burdens that arises when saving a large number of files.

More about it:

The network attached storage device is basically a server design single hardware system which is often termed as NAS head or NAS box. This NAS head mainly acts as an interface between the clients and the NAS. The network attached storage device does not require any assisting hardware like keyboard, mouse, monitor, etc. Instead of the full featured OS, the NAS normally runs an embedded OS which thus works independently without any troubles at some point of work.

One or multiple drives can be added to the network attached storage device to increase the storage capacity. Even the disk drives can also be added easily to the network attached storage device. Rather than adding to the individual storage device, most of the clients normally used to connect their computer device to the NAS head only.

The network attached storage device stores any number of data and any form of data like normal files, email files and boxes, website contents, system backup files and folders, etc. The use of a network attached storage device is similar to the vintage file servers only but the former is faster, comfortable and compatible with usage. The network attached storage device contains inbuilt multi functional applications with which the disk space clearance, disc space quotas, authentication, sending the mails automatically, alerts for incoming as well as outgoing mails, etc. are highly functional.


Depending on the manufacturer’s model, the network attached storage devices are available in three different types. They are as follows:

  • NAS based on embedded systems,
  • NAS based on the computer, and
  • NAS based on ASIC

In case of embedded system based NAS, certain embedded system like ARM, RTOS, MIPS, etc. were used for proper functioning of NAS. The energy consumption is much less in case of embedded based NAS and thus most clients prefers this model NAS server device.

The computer based NAS needs a separate software and hardware servers without which the NAS is highly impossible to function effectively. The energy consumption is a bit higher in case of computer based NAS, hence the preference is also less only.

In case of ASIC based NAS device, a single ASIC chip and hardware are used to implement the extra storage sever. This server consumes very less energy for it works and it is also an easy administrative processing system. Thus it became one another commonest storage server device which is used by most of the clients presently.

Benefits It Offer:

The network attached storage sever device is a simple and cheaper storage device which helps the customers to store large number of files in a compact and compatible manner. NAS mainly helps the network operating people who deals with a large number of file creating, file saving and file transfer works.

Thus it is clear that NAS or network attached storage is a brilliant option for those who are in need of higher storage for their day to day needs. This is a safer and cheap option that others.
