There's a significant problem right there. Not only will that configuration
badly degrade the performance of the RAID volume, it also compromises the goal
of redundancy which RAID-1 is supposed to provide.
Regards,
Disk are interweaved, so the performances are quite good (about 160% of
a single drive) and the redundancy is here. Any single drive can fail,
and the other two will be there to provide data.
Basically the first plesk is a-b-c, and the second is b-c-a, so
everything should be fine.
