What is RAID 1?
RAID 1 - Disk mirroring. Optimized for Redundancy
RAID 1 uses mirroring to write data to multiple drives. This means that when you write a file, the file is actually written to two disks. If one of the disks fails, you simply replace it and rebuild the mirror.
The tradeoff with RAID 1 is cost. With RAID 1, you must purchase double the amount of storage space that your data requires.
- Minimum number of drives: 2
- Strengths: Very high performance; Very high data protection; Very minimal penalty on write performance.
- Weaknesses: High redundancy cost overhead; Because all data is duplicated, twice the storage capacity is required.
