Consider the RAID level where block level striping is using with a parity disk. There are 6 data disks and one parity disk (7 disk in total). The parity disk is just storing parity information. Assume the data transfer rate of a single disk is 10 MB/sec. Assume there is a very large file. a) What is the maximum speed we can read the file. b) What is the maximum speed we can write into the file when we want to write very large amount of data.
