• A single drive failure in a RAID 1, 5 or 10 should not have caused this. Those raid levels have redundancy, so you can lose an entire drive and not have any problems (other than maybe speed)

    If losing a single drive in a RAID 1, 5 or 10 causes data loss or IO errors, then there's a bigger problem with that RAID array than a single failed drive. I think you might want to investigate further.
