  1. Let us assume we use RAID level 5 to store the following binary data:

01011111 00001010 11001101

10010001 00100001 11110011

Let us assume we have 4 disk drives, and the size of a strip is 8 bits. Illustrate how the data is stored on the 4 drives. Fill the table below. (10%)

(Note that in practice, a strip is much larger than 8 bits. A strip contains at least 1 sector, and a sector is typically 4096 bits.)
