Raid Research Essay Example for Free

Raid Research analyseThe word RAID stands for redundant ray of independent disks. Raid is usually utilize in environments with servers or at a business with large file servers, transaction of application servers, where data approachibility is critical, and shift margin is required. There are 8 types of foray intos, Raid 0 is technically not a burst level because it offers no fault tolerance but, it operates by providing data stripping which takes the information and spreads it out over all the disk drives. However, if one drive fails than the entire fall apart fails. Raid 1 is in addition referred to as disk mirroring it basically takes the information from one disk and stores it on multiple disks, this is great for fault tolerance because if one disk fails the information is on another disk. The only drawback to raid 1 is data access speed and the cost because there are more disks involved. Raid 5 is considerably the most unremarkably used Raid level simply because i t provides both stripping and parity. The parity block is distributed to all of the drives making it easier to access the information or have a balanced access load.The parity in raid 5 is used if one of the drives happens to fail, to recover that drive which makes the raid 5 the most common except the only drawback to this raid level is that it has a relatively slow write cycle. Lastly, RAID level 6 which is very similar to raid level 5 but provides two parity functions rather than scarce one. A minimum of four disks is required to create RAID level 6. Raid level 0, in time though it offers no redundancy, is still of use mainly to those who use applications that require high bandwidth such as data streaming or video editing software. Raid level 0 is also used because its most simple to implement. Raid level 1 is most expensive because it requires more disks to implement. It also requires heavy software manipulation and configuration to implement Raid level 1. If I were to purcha se raid it would absolutely be raid level 0 simply because its easy to implement and it would be effectual for my personal usage.
