The full form of DAS is “Direct Attached Storage.” DAS refers to a storage device that is directly connected to a computer.

These include HDDs, SSDs , and optical drives. By the way, DAS refers to internal storage devices, but it mostly describes external devices, such as an external hard drive .

The term “DAS” has been created to differentiate between network-attached storage ( NAS ) and direct-attached storage. Before the availability of NAS and storage area networks (SANs), direct-attached storage was the only option.

At the same time, DAS is still the most common type of storage, which is often used in personal computing, network and server administrators. Whereas most of the time we have to choose between DAS and NAS according to a storage solution .

The primary benefit of DAS and NAS is in the simplicity of its setup. You can easily connect a device with the computer, while it will also appear as an additional storage device if all the drivers needed are available.

Here, you do not have to configure network settings nor set up permissions for each individual computers .

DAS, which is the main drawback was that it only by the Computer Access may be that these are attached. At the same time, if you want that other systems can also access any connected DAS devices, then for this you have to configure the computer in the form of a file server.
