Why each option
To maintain space for 750GB of user data, creating a RAID 5 array using five 200GB disks is the best option available, providing both capacity and redundancy.
A RAID 5 array with five 200GB disks provides (5-1) * 200GB = 800GB of usable storage, which meets the 750GB requirement. RAID 5 offers good data protection through parity, allowing for the failure of one disk without data loss, making it a suitable and cost-effective solution for user data.
A JBOD (Just a Bunch Of Disks) configuration offers 800GB but provides no data redundancy; if any disk fails, data on that disk is lost, making it unsuitable for protecting user data.
