Raid Research Essay

The word fall apart stands for redundant ray of independent track records. burst is usu totallyy officed in environments with servers or at a barter with large file servers, transaction of application servers, where info admission priceibility is critical, and displacement adjustment is required. There are 8 types of raids, raid 0 is technically not a raid take aim because it offers no fault tolerance but, it operates by providing data stripping which takes the information and spreads it out over all the turn drives. However, if one drive fails than the entire raid fails. Raid 1 is also 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 exactly drawback to raid 1 is data access speed and the cost because there are more disks involved. Raid 5 is considerably the close commonly apply Raid level simply because it provides both stripping and parity. The parity block is distributed to all of the drives qualification 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 get hold that drive which makes the raid 5 the most common however 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 just one. A stripped-down of four disks is required to create RAID level 6. Raid level 0, even 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 go for. Raid level 1 is most expensive because it requires more disks to implement. It also requires heavy software manipulation and condition to implement Raid level 1. If I were to pur chase raid it would absolutely be raid level 0 simply because its easy to implement and it would be efficient for my personal usage.
