Concurrent users. This is possible due to the inclusion of a protocols accelerator and a session-aware traffic manager that determines the bandwidth/prority to associate with each session types. The upper-layer processor protocol accelerator provides processing of TCP/IP and UDP/IP protocols, which offloads the embedded application processor that is used for control and navigation functions. The TMA allocates system network, memory, and storage resources among both control and streaming-media sessions.

The result is hig-performancing DMC Soc that can accommodate many concurrent media sessions including several high-definitin video streams.

Besides serving mesia, the NAS40x enables the DMS application to protect media form data-loss because of a single HDD failure. Because of time and econmic considevations associated with acquired, tailoring, and formating media for enjoyable playback, the avoidance of data loss is an important concern among users, The NAS40x supports enhanced streaming RAID to ensure the media is protected from the time it is imported onto an NAS40x based media archive and continutes to be protected even during the failure f HDD from with the associated array. The user need not take any additional steps to protect media such as mirroring or backing up to other resources. Simillarly, no additional steps are needed to recovered media form data loss other then replacing the affected HDD at convenient time .The user never loses access to streaming media because of a single HDD failure with enhanced streaming RAID.

The software are NAS40X allows the users to parse files according to type(audio, video, still pictures), according to genre(action videos, co-medias), or according to title or author.

File Transfer using portable USB HDD: Media can be shared between networks using a portable USB HDD or Flash driver. Media can be read from the HDD or Flash drive and stored on the NAS40X controlled RAID5 HDDs and vice versa. Other media devices such as MP3 music players could be connected to the USB port to download music files from the RAID5 HDD array.
