Redundant array of independent disks (RAID) is a technique for storing the same data on multiple hard disks to increase read performance and fault tolerance. In a properly configured RAID storage system, the loss of any single disk will not interfere with users' ability to access the data stored on the failed disk.What Is RAID. RAID has been around for decades and is another virtualization process you can use to join disks to make larger arrays. RAID has many different features that you can exploit thanks to using multiple disk controllers. This includes setting up the array to still function after a disk failure by partially duplicating data. Types of RAID arrays .

While it doesn’t have the ability to reconstruct RAID arrays, it can easily recover data from individual drives using its sophisticated data recovery algorithms.RAID (redundant array of independent disks) is a setup consisting of multiple disks for data storage. They are linked together to prevent data loss and/or speed up …RAID 6 is also more expensive because of the two extra disks required for parity. RAID controller coprocessors often handle parity calculations and improve RAID 6 write speed. It takes a long time to rebuild the array after a disk failure because of RAID 6's slow write times. With even a moderate-sized array, rebuild times can stretch to 24 hours.RAID 5: Uses striping and parity across at least three disks to split data between two of the disks, while the third maintains parity data, allowing the array to be rebuilt if a drive fails. RAID 5 arrays offer fast read speeds but slower write speeds. RAID 6: Uses double parity striping across a minimum of four disks..
