Consider a RAID system with $6$ total disks, block size of $1KB,$ and chunk size of $4$ blocks.

The numbering of blocks on a particular disk will start at $0.$ We will call blocks $($storage locations$)$ on a particular

disk "disk blocks".

The numbering of blocks in the entire system also starts at $0,$ and counts up to the total number of blocks in the

system. We will call blocks $($units of data the system stores$)$ within the RAID system "data blocks".

$($a$)$ If the system is using RAID $0,$ where will a write to data block number $25$ change bits on disk? $($On which

disk$($s$)$ and in which disk block$($s$)$ internal to that disk?$)$

$($b$)$ If the system is using RAID $1,$ where will a write to data block number $25$ change bits on disk? $($On which

disk$($s$)$ and in which disk block$($s$)$ internal to that disk?$)$

$($c$)$ If the system is using RAID $4,$ where will a write to data block number $25$ change bits on disk? $($On which

disk$($s$)$ and in which disk block$($s$)$ internal to that disk?$)$

$($d$)$ If the system is using RAID $5,$ where will a write to data block number $25$ change bits on disk? $($On which

disk$($s$)$ and in which disk block$($s$)$ internal to that disk?$)$
