If your RAID controller fails, you have to find a compatible one to replace in order to get the RAID system to perform the way you set it up. Replacing failed disk is simple – Just plug it out and put in a new one.Īs hardware RAID requires additional controller hardware, the cost is higher than software RAID.
Thus, more space and speed can be used to read and write data. The RAID controller does not take processing power away from the disks it manages. Hardware RAID is dedicated processing system, using controllers or RAID cards to manage the RAID configuration independently from the operating system. The RAID can be implemented either using a special controller (hardware RAID), or by an operating system driver (software RAID).
It is a way to virtualize multiple, independent hard disk drives into one or more arrays to improve performance, capacity and reliability. RAID stands for Redundant Array of Inexpensive Disks.
