I need help with following question

1.You are designing a system that medical professionals will be using to obtain medical records. Thus, recovery from disk failures is extremely important. No data can be lost, and we are not evaluating speed or speed of recovery. Consider the 7 RAID schemes and SLED. You have 10 drives to work with

d.Which one would perform second best per this stipulation? My answer Raid 1

Please check if my answers are right

Thanks

Explanation / Answer

a. RAID 0 (no facility to withstand drive failure)

b.RAID 2( raid level which not currently in used because it stores error detection code which is just an overhead beacuse Modern HDDs use various correction and optymalising algorithms.)

c.RAID 1 (all data is stored twice once in original and once in mirror hence best for recovery from disk failures requirements.)

d.RAID 6 (writes parity data to two drives hence can withstand simultaneous failures of two drives )
