The new hard disk can be automatically written with the same data again using the stored data, without data loss and depending on the RAID system programming.

• RAID-0
  Redundant Array of Independent Disks-0
  Serves to accelerate the transfer rates, especially when reading large file formats. Strictly speaking, this system does not belong to the RAID group because it does not store any redundancy as a recovery. Two hard disks are written in parallel, if one breaks, everything is broken!

If you replace the defective disk with a new one, the data is copied back over from the functioning disk. The idea of ​​RAID-0 can also be added here, which doubles the access performance. However, it should be considered that if one hard disk has a sector error, it will be transferred to the other, and if data has viruses, it will also be copied to the other disk.

Using RAID-5 replaces these two.

• RAID-4
  Redundant Array of Independent Disks-4
  block-level striping with parity information on a separate hard disk. The same as with RAID-3, but not individual bytes but entire data blocks are written here.

• RAID-5
  Redundant Array of Independent Disks-5
  performance and parity, block-level striping with distributed parity information. Here the parity information is distributed to all hard disks, thus offering a high data throughput when reading data, redundancy is created in a distributed manner. https://de.wikipedia.org/wiki/RAID
