What is a NAS, and how does RAID work
NAS is an acronym for Network-attached storage. It actually represents a storage system for hard drives and can include different things within it, like configuration of RAID. When used in along side LAN IP, NAS can be configured to send different applications to network users spread across different workstations. NAS typically has its own set of programs for configuring file locations to different network attached equipment. This storage system is often included as a part of a more complete solution like SAN. NAS is so different from other forms of storage systems that different kinds of programs and OS that run on NAS serves limited purposes like data access, data's functionality, and supervision of different functionalities. A typical NAS unit doesn't limit clients to a single FTP. NAS systems typically incorporate one or more hard drives that are set into superfluous, and logical of storage containers or RAIDs. With NAS at your disposal, your responsibility of sharing several files across servers on a network is fully eliminated. This could also mean deployment through commercial embedded units or through those systems that run NAS programs. Contrary to a NAS system, RAID represents a system that is developed by combining several lower end hard drives to form a single storage device of larger magnitude. The device is known to provide superior performance, reliability and storage capacity, at least as compared to other forms of storage solutions. There are six distinct levels that have been developed in RAID, as agreed upon by numerous manufacturers world wide. The levels range from 0 to 5. Other combinations too are included in these levels including level 10 and level 6. In Level 0, data that is spread across different disks is striped without parity or redundancy. Maximum data transfer takes place in this level. This level is also known to handle large files in a good way. However, Spare drives are not so useful at this level. Level 1 is known to duplicate data across several disks. It effectively means that data can retrieved from a drive even if it is absent in another drive. This level is ideally suited for smaller applications. In Level 2, data is interleaved across many disks. All this while, parity information will be created using a code. This code is useful in detecting the error and the region where it has occurred. In Levels 3 and 4 too, data is striped across multiple drives. While the former is implemented at BYTE level, the latter is done at BLOCK level. These two levels are responsible for combining the performance that is seen in RAID 0. These two levels are ideal for large transfer sizes. Striping of parity information and data at BLOCK levels spread across many drives is seen in Level 5. RAIDs work at different levels as per the levels mentioned above. They can be implemented in software or hardware. While the software versions of RAID make use of computer's memory and CPU for its functions, the hardware versions make use of either internal or external RAID boards for its functioning.

Glyph PortaGig62 dual-drive RAID external hard drive $290.29 Glyph PortaGig 62 is modeled after it's powerful big brother the GT 062E, and offers capacities up to 3TB in a tiny footprint. With two internal SATA drives available in 7,200 and 5,400 RPM, the PortaGig 62 supports RAID 0, RAID 1, and Spanning modes. A built-in fan keeps the drives cool while Glyph Manager software constantly monitors the drive and enclosure health, notifying you if there is a problem. With capacities from 500GB, 1TB, and 1.5TBm, you will have more than enought room to back-up large sessions. Bus-powered with FireWire 800, the PortaGig 62 also includes USB and eSATA ports for optimum compatibility, allowing you to easily work on the road with a reliable RAID. Although eSATA is not a bus-powered interface, you can use the eSATA connection for fast data transfer (up to 177MB/s) while simultaneously using the FireWire 800 connection to power the drive. An external power supply is included with the PortaGig 62 if bus power is not available or is insufficient.A cool drive is a healthy driveThe PortaGig 62 uses a quiet internal fan for maximum airflow and proper cooling. The case is designed with front-panel ventilation holes to draw cool air in, while exhausting warm air out the back - critical to the performance and reliability of the components.3-2-1 warranty: best in the IndustryGlyph is so confident that their drive systems will perform at the most reliable level, they back them up with a 3-Year warranty, 2-Year Free Basic Data Recovery Policy, and 1-Year Advance Replacement (U.S. Continental 48 States only).Health Monitoring built inIf a drive in your PortaGig 62 experiences an issue, Glyph Manager software will warn you before it becomes a real problem. Along with setting the RAID mode, Glyph Manager constantly monitors Glyph drives using S.M.A.R.T. (industry-standard drive diagnostics), and reports the health to you. If a problem is detected, the front LED will blink red, and Glyph Manager software will alert you, allowing you to backup your data before any is lost. No other desktop drive has a diagnostic utility as smart as Glyph Manager.Designed and tested in the USAFirst Glyph selects the highest quality components available, then assemble the drives in their US factory, and perform regimented testing on every unit before it ships to you.*There is a current limitation with large volumes in Windows. PortaGig 62 does not show up correctly in Windows while connected via eSATA (Models above 2TB). Go to Glyph's knowledgebase for more information.**There is a current limitation with Pro Tools and volume size. Pro Tools does not support record or playback on volumes larger than 2TB. Go to Glyph's knowledgebase for more information.***Older versions of Windows, such as 2000 and XP |
