What is software RAID in Linux?
Linux Software RAID (often called mdraid or MD/RAID) makes the use of RAID possible without a hardware RAID controller. For this purpose, the storage media used for this (hard disks, SSDs and so forth) are simply connected to the computer as individual drives, somewhat like the direct SATA ports on the motherboard.

What is the difference between software RAID and hardware RAID?
1. Hardware RAID is a customized processing system, using different controllers or RAID cards to manage the RAID design independently from the OS. Software RAID uses the processing power of that computer’s operating system in which the RAID disks are installed.
