3 Question Which RAID types would use a minimum of four hard drives? (Choose all that apply). 10 6 0 ■ 51 5

Answer

Answer: 6, 10, 51 RAID stands for redundant array of independent disks. RAID 6: RAID stands for redundant array of independent disks. In raid 6 contains minimum number of 4 disks. This disk some time called as striping with double parity. It is like a raid 5, but the parity data is written in two separate drives. Hence it requires at least 4 drives and 2 drives can dying simultaneously. The main advantage of this Raid 6 is reading the data transactions are very fast RAID 10: Raid 10 is a combination of Raid 0 and Raid 1. This is also called as nested hybrid RAID configurations. This required latest 4 data drives to striping the data across each drive to speed up the data transfers. RAID 51: RAID 51 like RAID-1 type and it provides 1-based mirroring on each RAID 5 array. Hence it requires minimum of 4 disks to operate RAID 51 which is nothing but RAID 5+ RAID 1. It is mainly used for enhanced backup availability and high fault tolerance capabilities

Hence, the RAIDs 6, 10, 51 have minimum number of 4 drives to operate the data.
