A network attached storage or NAS is a storage device connected to a network with a ability to provide access to multiple authorized users or clients . That means it is like a private cloud network.It is inexpensive, more faster than other cloud based solutions and reliable. NAS storage is great for small business because they are not so expensive and easy to operate. Even we can use NAS in home as a automated backup system . Most of the people got confused with NAS, DAS and SAN. What is the difference between them ? Let’s take a look :
Difference between NAS and DAS :
DAS or Direct attached storage is a storage device that is not connected to a network. i.e. a USB stick, hard drive, flash drive all are DAS. You must have physical access to the device for transferring data. When served over network, NAS devices could have better performance than DAS .
Difference between NAS and SAN :
In both NAS and SAN or Storage Area Network, a centrelized data storage is shared between multiple devices via a network connection like LAN.In NAS, the storage is available to other computers as file-level but in SAN, the data is available as block-level , file system is handled in the client side. Most of the time, SAN uses fibre channel protocol for faster data transfer.
Advantages of NAS :
A NAS can be accessed by a multiple devices at the same time. It is extremely useful if you have a small business with multiple computers. You can use it as a central data backup storage or even as a media storage. You can store all of your movies and musics and access it from any device your computer, smart tv,smartphone or tablet pc. It is same as cloud storage. Cloud storage a re useful but they have many restrictions like storage limit, maximum number of devices can be connected at a same time, etc. Also cloud network speed is totally dependent on your internet network which is much slower than LAN .
Overall, if you are looking for a cheap, reliable ,fastest data storage system for your company or home, go for Network attached storage . In this post, we have picked out top 10 NAS storage available in the market currently. Take a look
