RAID 1+0 Volume Checking?

[Diakiaoshinsama]

Does RAID Level 1+0 need Volume Checking? I have the option in the Areca card that has a 12 TB 1+0 array. But since Volume Checking is needed to my knowledge only for Parity checking, and 1+0 has no parity that I know of, isn't the option completely not applicable?

never done it.

I suppose it could check the integrity by comparing the mirrors, but since there's no way to know which copy is right and which is wrong, correcting it is a crapshoot, unlike with parity. So probably you just get notified if any errors are found.

No.
