What data can be recovered in RAID 0?

Question

RAID

According to this guide

RAID 5 recovery is much more complex than RAID 0 is, as it adds the additional factor of parity and block rotation. RAID 0 only requires to find drive order and block size, but with RAID 5 there are 4 typical methods of block and parity rotation.

and google

Having data from the rest of the member disks you can try to recover files. However, only the files which are smaller than (N-1)*(block size) can be recovered. ... So in general, if one of the member disks fails beyond repair, it is impossible to recover data from RAID 0.

But I do not understand the formula that it considers. If I understood correctly, the file should not lie on the disk that failed. That is, its parts were placed on other disks.

Answer 1

If the content is unique, I would still advise you to use ride 10.
Temp more with 4 discs, ride 6 is meaningless.
Yes, it's expensive. But you'll get ride level 1 data integrity and ride level 0 read speed...
