Answer

100GB is the correct answer. Because RAID 5 means DISK STRIPING WITH SINGLE DISTRIBUTED PARITY. In this scenario we have 5 hard disks available to store the data and one hard disk we need to use for storing parity. so six harddisk - one harddesk ((6 *20) = 120 - one harddesk (20gb) .so remaining 5 hard desks size = 100 GB.

RAID 5 data space question needs to be reworded

Total Array Size:- 99.99GB

Total Usable Disk Space:- 93.12GB

120GB is Not a Correct Answer

Linux question was: How much usable space is available when a Linux system is configured with a RAID 5 array that consistes of 6 20GB drives. You give the answer of 120. I disagree / the question isn't clear there is a total of 120GB available however 1 drive is used for parity so that makes the total space available for user data 100GB.
