RAID was a protocol used to form bunch of disks. In case of Desktop PC's we do find 80GB, 160GB & 500GB etc HDD. But in servers 500GB is very small so it expects storage in 100TB's etc. But the present technology do no offer 100TB HDD. So we do apply this RAID logic to group HDD to make it visible as one HDD to OS.

Apart from grouping, RAID has following advantages
1. Data reliability
2. Performance

In general we have RAID controller cards which can fit in PCIe slots but we also have On Board RAID cores which comes with all the necessary SW. All we have to do is to set necessary permissions in BIOS.
simple and very useful.
