Question 17

You have three hard disks, each 1 TB in size. After installing them as a RAID-5 array in a computer, how much usable storage space will you have?

1.5 TB

2 TB

3 TB

Answer 17

2 TB

In a RAID-5 array, each stripe places data on n–1 disks, and parity computed from the data is placed on the remaining disk. The parity is interleaved across all the drives in the array so that neighbouring stripes have parity on different disks. Said differently, you lose the equivalent of one hard disk worth of storage to hold the parity information

Question 18
