NAS or Network Attached Storage is a kind of data storage that can be connected to a computing network without any fuss. NAS based units do not come equipped with monitor or keyboard and provides only file-oriented data storage services. These units are created using drivers of Linux operating systems or dedicated chips onto a microcomputer.
When it comes to storing data, NAS units usually uses the regular RAID. Therefore, any drive failure problem that takes place happens primarily due to improper functioning of the RAID. NAS drive recovery process is mostly handled by experts having experience in the RAID data recovery process. NAS can easily run through a dedicated chip along with its firmware. It is not only tailored exclusively for Linux. Data recovery is possible using several dedicated software tools, most common being ZAR.
The modern day NAS units typically feature tailored installation of Linux for handling RAID. The components used for RAID enabled computers may not be seen on regular PCs. The less expensive NAS devices use system on the chip design, PPC, or ARM processor. However, even then, these devices are controlled by the LINUX. With standard software tools being used, the discs from NAS unit can be easily mounted on any LINUX system with minimal effort.
