For SBD configuration, can we use three different disks from three different tiers?

For SBD configuration, can we use three different disks from three different tiers, with different speed and with different size?
OS is SUSE 15 SP1

I am not sure what you mean by different tiers, but speed and size should not matter.

Here tiers means emc or other vendor’s storage level tier1, tier2 like this.

I don’t see why that wouldn’t work.

my only question is about the performance impact on cluster.
