RAID is the acronym for redundant array of inexpensive disks. RAID is a data storage mechanism for improving performance and fault tolerance on computing systems.
Hardware RAIDs
Emerged somewhen in 1980s and, initially, was the only way to do it. There two challenges with hardware RAIDs:
- When hardware RAID goes down, you need to find and buy the same make and model of that card. If the hardware RAID is several years old, those cards may no longer be available.
- When the architecture needs to be rebuilt, hardware RAID limits that possibility.
Software RAIDs
Software RAIDs refer to those RAIDs that software manages.
