Software RAID is the RAID configuration done through the OS feature or a utility installed after the OS is installed. If the OS gets corrupted by Virus or OS crashes, the Software RAID will also crash and creates a issue in recovering the data and there will be an additional load on the server for RAID functionality. Also the same software utility has to be used to recover the data. In case of Hardware RAID, the RAID hardware has the controller which works independent of the OS and any OS craches will not affect the data for recovering the same and there will be no additional load on the server for this functionality. In Hardware RAID if OS crashes, we can install the OS without recreating the RAID array and start working in the server.
