DAS (Direct Attached Storage) is one amongst the Storage solutions. The server structure of this storage solution is similar to PC structure, external data storage devices (such as disk arrays, optical drives, tape recorders, etc.) are directly articulated within the server bus. The data storage device may be a part of the entire server structures. The server also shoulders the responsibility of the full network data storage.

DAS is well suited for a small-to-medium-sized business where sufficient amounts of storage can be configured at a low startup cost. The DAS enclosure will be a separate adjacent cabinet that contains the additional disk drives.

NAS (Network Attached Storage) comprehensively improve the inefficient storage way of DAS previously. It adopts a kind of file server that is specially developed for network data Storage and is independent of the PC server. All of the network data storage devices (such as a variety of disk arrays, tape, we, etc.) are concentrated within the NAS server, thus the storage capacity are often well extended. At the same time, due to this way of network storage is independently assumed by the NAS server, so basically there is no influence on the performance of the original network server. And therefore entire network performance is not affected.
