RAID array is an acronym that stands for redundant array of independent (or inexpensive) disks. This is a method of organizing computer data into multiple disks and hard drives in order to create copies of that data by storing it on those various disks. RAID is used as a way of enhancing computer performance by allowing the computer to run more efficiently and is available in nearly a dozen different levels. It can be installed on both personal computers and small business or corporate servers in order to allow multiple computers to run smoothly at once while also creating a data backup system. Although RAID on its own is not recommended to be relied on as a sole backup service, in the event of hard drive crash or malfunction it can act as a saving grace.
RAID level 0 and 1 are most commonly used on personal computers whereas RAID levels 5, 6 and up are used for servers that multiple computers connect to and rely on. Servers can run on dozens of computers at once and serve as the basis for computer-reliant employees of most companies. When RAID 5 is installed on business servers it increases function, productivity and allows for copies of that server’s data to be created. The hard drive space of the server is optimized while data is effectively stored and copied.
RAID 5 relies on three or more hard drives so in the event of a crash or malfunction, data recovery specialists can be contacted to recover data that has been
