If you have four 1TB hard drives in a single array, which one of the following standard configurations gives you the most redundancy?
- RAID 5
- JBOD
- RAID 6
- RAID 0
EXPLANATION
EXPLANATION
Only Raid 5 and Raid 6 give you redundancy. Regardless of size and performance, Raid 6 is fault tolerant to 2 disks failing, while Raid 5 is only fault tolerant to 1 disk failure.JBOD "Just a Bunch Of Disks" (Standard not Hybrid) doesn't offer redundancy.
RAID 0 Offers performance gains by striping, but doesn't offer redundancy.
RAID 5 Offers a larger total drive size but only 1 drive of redundancy.
RAID 6 Requires at least 4 drives and has an extra drive of redundancy.
