What is RAID (redundant series of independent disks)?
Raid, which means a redundant series of independent (or cheap, depending on who you are asking), is the category of disk units that use two or more hard drives to ensure that the data is safely stored.
There are several different RAID levels, each with its own specific data protection method stored on each hard disk. Some of the most commonly used are:
RAID 0 : This type contains data streaming that spreads parts of the file via multiple units. This is used to increase performance, but if one unit fails, the data in the field is lost. This ensures that all data are duplicated on both units, and if one unit fails, the other will have a backup. It also helps to increase performance.S by disk failure, data from this unit can be restored to the replacement disc that is formed when an error is found. However, the process of making a replacement disk can cause problems such as the slowdown of performance.
Raid 5 : This is perhaps the most popular type of Raid field. This type contains Stripping RAID 0 as well as error correction, resulting in a combination of excellent performance and failure tolerance.
Using RAID in personal computers is slowly on the rise. Previously, the higher cost of hard drives compatible with RAID undesirable to the general public. RAID is widely used in top -class computers and business computing environments; It is slowly looking for land in the home because prices are still decreasing.
Thecombination of high performance and data protection makes RAID a heavy choice to refuse, especially, because more and more people depend on hard drives to keep important data safe.
