[Scots, raid on horseback, from Middle English rade, from Old English rād, a riding, road; see reidh- in Indo-European roots.] raid′er n.Word History: Raid and road both descend from the Old English word rād, which meant primarily "the act of riding" but could also be used specifically to describe an act of riding with hostile intent—that is, a raid. The ai in raid represents the standard development of the Old English vowel ā in Scots and the dialects of northern England, while the oa in road represents the standard development of Old English ā in the dialects of southern England. In the dialects of southern England, road retained its earlier senses of "journey on horseback" and "hostile foray" until the mid-1600s, when the modern sense "public way" became the most common meaning of the word. Later, Sir Walter Scott (1771-1832) helped popularize the northern form of the word, raid, through his collections of Scots ballads and his other writings. In the meaning "a military expedition on horseback," raid became part of the general vocabulary of English outside of Scotland and northern England. A trace of the earlier meaning of road, "foray, raid," can still be detected in the compound inroad, literally "a riding or advance into."raid (reɪd) n1. a sudden surprise attack: an air raid. 2. a surprise visit by police searching for criminals or illicit goods: a fraud-squad raid. vb3. to make a raid against (a person, thing, etc)4. to sneak into (a place) in order to take something, steal, etc: raiding the larder. [C15: Scottish dialect, from Old English rād military expedition; see road] ˈraider nraid (reɪd) n. 1. a sudden assault or attack, as upon something to be seized or suppressed: a police raid on a narcotics ring. 2. a sudden attack on an enemy, as by air or by a small land force. 3. an effort to lure away a competitor's employees, members, etc. 4. a concerted attempt of speculators to force stock prices down. v.t. 5. to make a raid on. v.i. 6. to engage in a raid. [1375–1425; Middle English (north and Scots) ra(i)de, Old English rād expedition, literally, a riding; doublet of road] raidAn operation, usually small scale, involving a swift penetration of hostile territory to secure information, confuse the enemy, or to destroy installations. It ends with a planned withdrawal upon completion of the assigned mission.raid Past participle: raided Gerund: raiding

RAID
RAID[rād] (computer science) A group of hard disks that operate together to improve performance or provide fault tolerance and error recovery through data striping, mirroring, and other techniques. Derived from redundant array of inexpensive disks. Raid a penetration into the enemy rear by mobile tank, mechanized, cavalry, and partisan units for the purpose of inflicting losses; destroying important installations, such as bridges, airfields, railroads, communication lines, warehouses, and supply bases; disrupting the work of supply and evacuation routes; supporting or organizing partisan movements; and diverting enemy forces. Raids have been used in many wars. The raids by Russian cavalry detachments, such as D. V. Davydov and M. I. Platov’s cossacks in the rear of the French Army in the Patriotic War of 1812, and the large-scale cavalry raids of the Civil War of 1918–20 are well known. During the Great Patriotic War (1941–45) raids were made by Soviet cavalry units, for example, the raid by General P. A. Belov’s cavalry corps in 1942, and by many partisan units. RAIDRedundant Arrays of Independent DisksRAID(Redundant Array of Independent Disks) A disk or solid state drive (SSD) subsystem that increases performance or provides fault tolerance or both. RAID uses two or more physical drives and a RAID controller, which is plugged into motherboards that do not have RAID circuits. Today, most motherboards have built-in RAID but not necessarily every RAID configuration (see below). In the past, RAID was also accomplished by software only but was much slower. In the late 1980s, the "I" in RAID stood for "inexpensive" but was later changed to "independent."
In large storage area networks (SANs), floor-standing RAID units are common with terabytes of storage and huge amounts of cache memory. RAID is also used in desktop computers by gamers for speed and by business users for reliability. Following are the various RAID configurations. See NAS and SAN.

EMC has been a leader in high-end RAID systems for years with systems storing multiple terabytes of data. (Image courtesy of EMC Corporation.) |
RAID 0 - Striping for Performance (Popular) Widely used for gaming, striping interleaves data across multiple drives for performance. However, there are no safeguards against failure. See RAID 0.

RAID 1 - Mirroring for Fault Tolerance (Popular) Widely used, RAID 1 writes two drives at the same time. It provides the highest reliability but doubles the number of drives needed.
RAID 10 combines RAID 1 mirroring with RAID 0 striping for both safety and performance. See RAID 1 and RAID 10.

RAID 3 - Speed and Fault Tolerance Data are striped across three or more drives for performance, and parity is computed for safety. Similar to RAID 3, RAID 4 uses block level striping but is not as popular. See RAID 3 and RAID parity.

RAID 5 - Speed and Fault Tolerance (Popular) Data are striped across three or more drives for performance, and parity is computed for safety. RAID 5 is similar to RAID 3, except that the parity is distributed to all drives. RAID 6 offers more reliability than RAID 5 by performing more parity computations. For more details, see RAID 5.
