as hardware raid, and features are not as good as hardware raid. Next we will introduce various RAID technologies I. RAID 0 The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done. The structure is as follows. Ii. Raid
