There are different kinds of storage options and each one of them provides advantages of their own. Following is the difference between NAS with two particular storage alternatives; directly-attached storage (DAS) and storage-area network (SAN) and how they facilitate each user in a distinct way.
NAS And DAS
While NAS is a committed file storage that allows multiple users and heterogeneous client devices to utilize data from a common disk capacity or from a device that is connected to the similar network, DAS or directly-attached storage works a little differently. DAS is also a committed server or a dedicated storage device which on the contrary, is not connected to a network. To elaborate more, DAS is merely an extension of a current server and may not be networked. A common example of DAS would be a computer’s hard drive.
While both NAS and SAN can substantially increase the storage size by RAID or clustering, DAS functions better than NAS when it comes to computer-related software. Furthermore, installing DAS is also easier as compared to NAS as all a user has to do is buying the drives that he needs to attach to the insert.

Furthermore, when connected to a server, NAS has a better performance than SAN and also renders the advantage of sharing storage with several users.
NAS And SAN
While NAS works by offering both storage and a file system, SAN (storage area network) offers only storage and that too block-based, leaving the clients to deal with the file system. To put it more simply, SAN works on various storage alternatives on a liberated, advanced network.
Another difference commonly observed between NAS and SAN is that the former organizes I/O requests for separate files whereas the latter handles the similar requests on adjacent units of data.
