A.Overcoming the performance bottleneck of the target disk (hot spare disk) of traditional RAID reconstruction, so that the write bandwidth of the reconstructed data stream no longer becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed and reduces the failure of double disks. Probability, which improves the reliability of the storage system.

B.The data is automatically and evenly distributed on the hard disks in the storage pool, avoiding unevenness of the hard disks, thereby reducing the overall failure rate of the storage system

C.The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots and greatly improving the performance and capacity of a single LUN.

D.There is no write penalty in RAID 2.0+, which overcomes the impact of write penalty in RAID 5 and RAID 6 levels in traditional RAID technology on LUN write performance, and greatly improves LUN performance
