RAID (Redundant Array of Independent Disks) is a storage protocol that combines multiple disks into a single virtual disk. When you create RAID, you combine multiple disks into a single virtual disk so that you have faster read and write speeds, as well as data protection. RAID is designed to combine the disk read/write performance and ensure data redundancy. But on the downside, RAID will also create a single point of failure.
If one disk fails, all the data on the virtual disk will be lost. That’s why RAID is mostly used to boost read/write performance and to protect data from accidental data loss. That said, if your RAID is failing, you may need a professional to recover your data.… Read the rest
