Absence of redundant array of independent drives enhances the risk loss of data. Nowadays, an organization accumulates data, analyze its benefits and then go for measures that have the capability to safeguard its investment portfolio. Along with, it needs to be done in a seamless manner without knowledge of the user. RAID 5 helps a lot in this.
The RAID technology came into existence with strenuous attempts by scientists to generate large disk drive storage systems by utilizing cheap small drives. The storage capacity of computer can be increased and the response time of computer is reduced while storing as well as retrieving data by using RAID 5. Process used to recover data and recover files in this platform is not equally advanced. As a result raid recovery software is available in the market.
According to the Seagate, data blocks to every disk drive contained in a collection of drives are written by RAID technology. After writing, the data blocks to last disk drive in collection. When other data exists, writing is started over the first drive. This process doesn't discontinue until the writing operation of computer is not completed. This system is known as striping. Most of the patterns of RAID technology are composed of RAID0, RAID1 as well as RAID5. RAID 1 copies data across the all drives.
Three or more drives are utilized by RAID5 for protecting data contained in a collection of drives. Data is extended throughout the collection of drives. Moreover, parity checking is constantly executed by the computer. Thought this checking, a calculation is done on bits of data for figuring data errors. According to the Seagate, parity information can also be amassed on every drive. Due to this process, the data included on failed disk drive is reconstructed.
If a drive is failed in the environment of RAID5, there is need to replace failed disk drive while computer system is continuing for accessing rebuilt data on operational drives. This process is known as hot swap. Once the new disk drive is fixed, RAID5 starts the procedure that refills data as well as parity information to the disk drive.
