Webb16 feb. 2012 · RAID-1: This type is also known as disk mirroring and consists of at least two drives that duplicate the storage of data. There is no striping. Read performance is improved since either disk can be read at the same time, meaning if one disk is busy the other is accessed. Write performance is the same as for single disk storage.

Webb11 juni 2024 · Set up two sets of two drives in RAID 1. This means that one disk could fail in either pool, and you would have data redundancy. Now, set the two pools of drives in RAID 0.
