RAID on Security+
I have taken the Security+ exam twice now. Last time I took it, I scored a 730. I am set to take it again on the 13th. Each time I have taken the exam, I have gotten a productivity question relating to RAID. However, I haven't found any good sources to explain RAID and would really like to have a good understanding of it going in to the exam this time-- this question could be the difference between pass and fail for me. Can anyone point me in the direction of a good source for learning more about RAID configurations? Thank you!
