	RAID - Wikipedia, the free encyclopedia
		RAID 0 is useful for setups such as large read-only NFS servers where mounting many disks is time-consuming or impossible and redundancy is irrelevant.
		RAID 5 implementations suffer from poor performance when faced with a workload which includes many writes which are smaller than the capacity of a single stripe; this is because parity must be updated on each write, requiring read-modify-write sequences for both the data block and the parity block.
		RAID 6 is inefficient when used with a small number of drives but as arrays become bigger and have more drives the loss in storage capacity becomes less important and the probability of two disks failing at once is bigger.

	RAID controller - Wikipedia, the free encyclopedia
		A RAID controller is a device which manages the physical storage units in a RAID system and presents them to the computer as logical units.
		The controller can be internal to a computer, either as an Expansion card or embedded on the motherboard, or it can be located in an independent enclosure, such as a disk array or NAS (network-attached storage) server.
		RAID adapters for use internal to a PC or server are often sold as separate commodities to which commodity disk drives are attached.

		RAID Controller SRCU41L provides an intelligent storage solution for mission-critical servers by protecting vital data while offloading RAID processing from the server.
		The controller also supports the Intel® RAID Web Console, a GUI-based tool that provides a central, unified environment for simplifying the management of remote servers on a network and other critical monitoring and management activities.
		RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.

	RAID and Data Protection Solutions for Linux
		RAID, short for Redundant Array of Inexpensive Disks, is a method whereby information is spread across several disks, using techniques such as disk striping (RAID Level 0) and disk mirroring (RAID level 1) to achieve redundancy, lower latency and/or higher bandwidth for reading and/or writing, and recoverability from hard-disk crashes.
		RAID Reviews contains some product reviews and performance benchmarks, circa 1998, that were originally a part of this web page.
		Linux RAID devices cannot be dynamically resized, nor is it easy to move a RAID array from one set of drives to another.

	3ware SATA RAID Controller family from AMCC Storage
		When the challenge is to increase storage capacity while controlling costs, the Escalade 8000 Series delivers the best value, high-capacity SATA controllers.
		RAID reliability is compromised with software RAID, as the RAID system is vulnerable to an operating system corruption or crash.
		StorSwitch allows the controller to simultaneously communicate with all drives, scaling linearly as more drives are added, resulting in the highest possible storage subsystem performance.

	Apple - Xserve RAID
		Xserve RAID drives feature true hot-swapping capabilities that allow you to remove and replace a failed drive without losing data or interrupting service, thanks to the hardware RAID controller and the Apple-designed drive carrier.
		With Xserve RAID, the system continues to operate while the contents of the failed drive are rebuilt on a replacement drive, using redundant or parity information.
		Xserve RAID supports RAID levels 0, 1, 3, 5 and 0+1 using the hardware RAID processor, and supports levels 10, 30 and 50 combining hardware RAID capabilities with software RAID in Mac OS X. In addition, Xserve RAID works well paired with Windows, Linux or NetWare servers, making it perfect for mission-critical data storage.

	Adaptec AAA-UDMA RAID Controller - PCStats.com
		The controller is the AAA-UDMA, a four-channel UDMA/66 RAID controller supporting up to four hard drives in RAID 0, RAID 1, RAID 0/1, and RAID 5 configurations.
		SCSI controllers can have 15 or more devices per channel (depending on exactly which type of SCSI is used), and since arrays can span multiple channels and even multiple cards in high-end configurations, SCSI RAID arrays consisting of tens of drives are not uncommon in large servers.
		And since even a single-channel SCSI controller can hold many more than four drives, this ATA solution is strictly intended for small servers for those on a budget.
