back to top What is RAID? What are its benefits?

Celeros - Bringing SANity to Storage Costs
The fundamental principle behind RAID (Redundant Array of Independent/Inexpensive Disks) is that it allows a collection of individual disks to behave as one larger, faster, and more reliable disk. Thus capacity, performance, security, and reliability of the disk subsystems exceed that of its constituents. Once almost exclusively the province of expensive SCSI disks, RAID has gained in popularity with the steady increase in the affordability and performance of ATA drives.

What is RAID?

Kaleidescape - FAQ (Frequently Asked Questions)
Redundant Array of Independent (or Inexpensive) Disks. A storage system that employs two or more disk drives in combination for fault tolerance and (sometimes) increased performance. RAID storage systems are frequently used on servers, especially for enterprise applications.

Q26. What are the different RAID levels and what are the benefits of different RAID levels?

welcome
RAID level 0 offers no redundancy and is sometimes called striping. This RAID level offers the highest level of performance compared to the other RAID levels. It also offers the lowest cost per megabyte, as no extra storage is required for fault tolerance. A minimum of two hard disk drives is required and you can have as many drives in the RAID 0 array as are supported by the RAID controller card. This level is good for applications that don't require any data redundancy.

Q8. What are the benefits of hardware RAID over software RAID?

welcome
A8. All AMCC 3ware RAID controllers are hardware RAID controllers. They incorporate onboard processors which manage I/O functions. The PC and Apple workstations' system CPU is free to manage your vital audio, video, and other capacity hungry applications for optimized overall system performance.

Ultera Systems | Frequently Asked Questions, Virtual Tape St...
Ultera's Optical RAID controller solutions virtualize an array of optical devices using RAID (Redundant Array of Independent Devices) to operate as a single logical optical drive. Seen by the host as a single optical drive with increased performance, online storage capacity & reliability. Optical Striping (RAID Level 0) increases performance and online storage capacity up to 4 times more than a single optical drive.

Mendax - Frequently Asked Questions
In computing, a redundant array of independent disks (more commonly known as a RAID) is a system of using multiple hard drives for sharing or replicating data among the drives. Depending on the version chosen the benefit of RAID is a one or more of increased data integrity, fault-tolerance, throughput or capacity compared to single drives.

KODAK:FAQ:Teleradiology
RAID stands for "Redundant Array of Inexpensive (or Identical) Disks." RAID employs a group of hard disks and a system that sorts and stores data in various forms to improve data-acquisition speed and provide improved data protection. To accomplish this, a system of levels (from 1 to 5) "mirrors," "stripes," and "duplexes" data onto a group of hard disks.

RAID - Redundant Array of Independent Disks - is an evolving storage technology that offers significant advantages in performance, capacity, reliability, and scalability to groups of users that have requirements beyond those offered by a single PC. RAID systems provide high reliability and data availability through techniques such as parity checking. In this scheme, when the RAID controller writes information onto the disks, it also writes redundant information called parity bits.

FAST - Knowledge Center
It is short for "redundant array of independent disks" - a configuration of multiple drives used to provide fault tolerance (via mirroring or parity checking) or higher performance (via striping). RAID 5, with striping and parity checking, is frequently used to increase search-engine performance and provide a certain level of redundancy.

Raid FAQ
To some a raid may be a whole lot of folks getting together for a common purpose, in CoF it's a pre-planned gathering for a common purpose. The number of people does not matter. Of course, the more the merrier. In other words, a raid can be just a single group, but of course then can't accomplish as much as 2 or 3 groups could. There is always one person in charge of the raid, this is the Raid Leader. The Raid Leader is the one that plans the raid and runs it.

RAID is a hard disk configuration that allows multiple drives to be combined into one larger or more reliable logical volume. For example, using RAID you can combine two 160gb drives into a 320gb drive, or combine three drives into a 320gb drive with a spare drive to garuntee data reliability. RAID configuration is available on Jumpline.com dedicated servers to insure the most space for your applications and to prevent data loss.

Raiding is a term meaning you travel to another village, and battle whomever you can from that village. You will be able to gain one village point per kill every 200 seconds, however if you reside in Horizon, you are allowed to gain a village point every time you kill someone. They have no time limit. Raiders from other villages will also be able to attack your village. You can tell the difference between your villagers, outlaws and raiders in the scout area page and the users in town page.

But why do you have changelog entries for RAID hardware?

Darik's Boot and Nuke FAQ
DBAN does indeed have native drivers for most RAID implementations, but making it run can require configuration changes on the host. I cannot help if you lack enough clue to do this because I do not have hardware samples for development and testing. Send hardware if you want support for this equipment. I started DBAN from a floppy drive, but it says "a floppy disk in DOS format was not found" after the wipe.

What happens when you go to film festivals? What was it like to raid Sundance?

Guerrilla Girls: Frequently Asked Questions
Is was a real rush to work behind the scenes at Sundance, putting up our stickers on bulletin boards, in bathrooms and on movie posters. Then we'd hurry back to our hotel rooms and log on to Indie Wire to read what they were saying about our caper, then check our email for press responses. Our stickers went all the way to New Zealand and we got an angry letter from a theater owner claiming that the film industry there wasn't nearly as bad as Hollywood. Great to snag him into the discourse!

How does SpinRite operate with RAID arrays?

GRC | SpinRite 6.0 FAQ - Frequently Asked Questions
SpinRite is able to operate upon drives behind a thin RAID-0 controller configuration without any modification. By a "thin controller" we mean a controller like an add-on Promise controller, or typical RAID controller built into a motherboard. Specifically, one that is not providing its own high-end microprocessor with megs of independent RAID caching RAM memory.

What is RAID and how would it help me?

Welcome to CSInet Internet Access!!
RAID, or Redundant Array of Inexpensive Disks, provides fault tolerance in the event of a hard drive failure. We offer servers with RAID 1 (mirroring) and RAID 5 (striping with parity). If hard drive in a RAID 1 fails, the second hard drive will take over. This insures that the server will continue to function, and that no data will be lost. RAID 5 uses a group of hard drives and reads and writes data to each simultaneously.

What are raid quests?

WoW -> Info -> F.A.Q. -> Quests
These special quests, which have the "Raid" designation in your quest log, require raid groups of over five players to complete. Some raid quests are even designed for 40 players! Raid quests are few in number but the rewards are extremely powerful. Note that if a quest is not labeled a raid quest, it cannot be completed while in a raid.
