Could a RAID Level 1 organizat

[问答题]
Could a RAID Level 1 organization achieve better performance for read requests than a RAID Level O organization (with nonredundant striping
of data)? If so, how?
推荐
Yes, a RAID Level 1 organization could achieve better performance for read requests. When a read operation is performed, a RAID Level 1 system can decide which of the two copies of the block should be accessed to satisfy the request. This choice could be based on the current location of the disk head and could therefore result in performance optimizations by choosing a disk head which is closer to the target data.
