It is often manufactured as a computer appliance — a purpose-built specialized computer. Network-attached storage removes the responsibility of file serving from other servers on the network. From the mids, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers. Potential benefits of dedicated network-attached storage, compared to general-purpose servers also serving files, include faster data access, easier administration, and simple configuration.
The hard disk drives with 'NAS' in their name are functionally similar to other drives but may have different firmware, vibration tolerance, or power dissipation to make them more suitable for use in RAID arrays, which are often used in NAS implementations.
In a non-RAID application, it may be important for a disk drive to go to great lengths to successfully read a problematic storage block, even if it takes several seconds. In an appropriately configured RAID array, a single bad block on a single drive can be recovered completely via the redundancy encoded across the RAID set.
If a drive spends several seconds executing extensive retries it might cause the RAID controller to flag the drive as 'down' whereas if it simply replied promptly that the block of data had a checksum error, the RAID controller would use the redundant data on the other drives to correct the error and continue without any problem. Such a 'NAS' SATA hard disk drive can be used as an internal PC hard drive, without any problems or adjustments needed, as it simply supports additional options and may possibly be built to a higher quality standard particularly if accompanied by a higher quoted MTBF figure and higher price than a regular consumer drive.
A NAS unit is a computer connected to a network that provides only file-based data storage services to other devices on the network. Although it may technically be possible to run other software on a NAS unit, it is usually not designed to be a general-purpose server. For example, NAS units usually do not have a keyboard or display, and are controlled and configured over the network, often using a browser.
A full-featured operating system is not needed on a NAS device, so often a stripped-down operating system is used. NAS units rarely limit clients to a single protocol. NAS is designed as an easy and self-contained solution for sharing files over the network.
When both are served over the network, NAS could have better performance than DAS, because the NAS device can be tuned precisely for file serving which is less likely to happen on a server responsible for other processing. NAS is generally not as customizable in terms of hardware CPU, memory, storage components or software extensions, plug-ins, additional protocols as a general-purpose server supplied with DAS. Indeed, in his songs Nas talks about serious things, nevertheless the despair is not the key word: there is always hope for the best.
They signed the contract with Dr. Later Cormega quitted the band, and his place was taken by Nature. That album was certified platinum, however the musicians decided to split and to work on their solo projects. In Nas co-wrote and starred in the movie Belly, directed by Harold Williams. A year later the musician released his album I Am The Autobiography , with every track describing some part of his life. By Nas and Jay-Z had an intense relationship, and everybody found out about their feud after the songs, in which both rappers mocked each other.
In Nasir married rhythm and blues singer Kelis. On April, Kelis filed for divorce, and on July she gave birth to their son, Knight. Digital download. Production for the album took place during to and was handled primarily by Damian Marley and Stephen Marley. Fusing musical elements of hip hop and reggae, Distant Relatives features lyrical themes concerning ancestry, poverty, and the plight of Africa.
