While backups will insure you from data loss, restoring large amounts of data (in the event of drive failure, for example) can take many hours to perform. If those backups are hours or days old, you will lose all of the data stored or changed since the last backup. With RAID, you can weather the failure of one or more drives without data loss and, in many instances, without any downtime.  A RAID controller can also be software-only, relying on the host system’s hardware resources, mainly the CPU and DRAM. Software-based RAID is identical to hardware-based RAID in terms of functionality, but its performance is frequently less than that of the hardware variants.Because no extra hardware is required, the key advantages of employing a software RAID controller are flexibility and low cost. It is critical, however, to verify that the host system’s CPU is capable of executing the RAID software without degrading the performance of other applications on the system.
