Answer: A) Very good on reads and D) Parity on separate disk
Explanation:
RAID-5 uses the disk striping with parity and it is a independent disk arrangement of the redundant array. As, the parity and data are placed in an even manner over the disk, in such a way that the bottleneck frame is not present in any disk.
In case of disk failure, the management of data can still be done with the help of stripping. Combination of parity and data stripping is one of the main advantage of RAID-5 and it is also very good in reading the data.
