What is the minimum number of disks required in a fully redundant RAID5 array?
A RAID5 array requires a minimum of three disks to be fully redundant. RAID5 uses striping with parity, storing parity information across all the disks so that data can be reconstructed in the event of a single disk failure. With three disks, RAID5 can maintain redundancy while utilizing the storage capacity effectively.
C - 100%
3 disk. Speed gain 2x read speed, no write speed gain Fault tolerance 1-drive failure
The answer is C :) In order for RAID to provide any kind of redundancy to logical disks, there must obviously be at the very least two physical block devices (three for RAID5) in the array to establish redundancy, ergo protection. https://lpic2book.github.io/src/lpic2.204.1/?h=mdadm#mdadm
3, so C is correct.
C - 3 is correct
