RAID stands for Redundant Array of Inexpensive Disks. In general, a RAID-enabled system uses two or more hard disks to improve the performance or provide some level of fault tolerance for a machine.
- Fault tolerance providing a safety net for failed hardware by ensuing that the machine with failed component, usually a hard drive, can still operate.
- Fault tolerance lessens interruptions in productivity , and it also decreases the chance of data loss.
You can setup a single disk with two partitions: one to boot from and ohter for data storage and have the data partition mirrored.
- It also matters whether you have hardware or software RAID, because software supports fewer levels than hardware based RAID. Different controllers support different levels of RAID and also dictate the kinds of disks you can use in an array- SAS, SATA or SSD
