There are two disadvantages of just mirroring your data on additional internal disks: your backup is physically in the same location so if the PC gets stolen or there is a A simultaneous read request for block B1 would have to wait, but a read request for B2 could be serviced concurrently by disk 1.

Just use RAID10, most people know that this means mirrors that are striped. d 0 {\displaystyle d_{k-1}d_{k-2}...d_{0}} in base 2 where each d i {\displaystyle d_{i}} is either 0 or 1. This detects bad blocks before use.[67] Data scrubbing checks for bad blocks on each storage device in an array, but also uses the redundancy of the array to recover bad blocks

It is a safeguard when the storage system gets stolen. The array is still usable in the meantime. Often extra cache memory is used on these controllers to improve the write performance. news In a RAID01 you need to recover the full mirror (like in RAID01 mode).
