Hello, friend!

Multiple copies: One data copy has multiple identical copies, which are stored on different storage nodes in a distributed system.

RAID: The redundant array of disks (Redundant Array of Inexpensive/Independent Disks) combines multiple disks into a large disk with large capacity, high read/write speed, and good fault tolerance.

RAID technology has evolved and now has six defined standard RAID levels ranging from RAID 0 to 5.

In addition, there are 6, 7, 10 (a combination of RAID 1 and RAID 0), 01 (a combination of RAID 0 and RAID 1), 30 (a combination of RAID 3 and RAID 0), and 50 (a combination of RAID 0 and RAID 5).

Different RAID levels represent different storage performance, data security, and storage costs.

If you want to know more information about RAID, see RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10.

Hope this helps!
