Question # 35

The following description about RAID is correct (multiple choice) BC

Compared with RAID5, RAID6 has stronger data recovery ability, but the read and write ability of the disk is reduced

When a disk is damaged, other disks in RAID5 can still work normally, and the disk I/O performance Can be unaffected

RAID improves the I/O performance of the storage system by concurrently reading and writing data on multiple disks

RAID can be regarded as a storage space composed of two or more disks, and its usable capacity is Sum of disk capacity
