Can x318 and x376 disks be used as hot spare with each other?

A 8TB X318 disk is supported by DS212C shelf, and a 8TB X376 disk is supported by DS460C shelf. we plan to connect a DS212C shelf and a DS460C shelf to FAS2620 in the same stack. As per HWU, the difference of X318 and X376 disk is disk interface speed (X318 suports 12,6&3GB, X376 suports 12GB).  Can two types disks be used as hot spare disk with each other?

Thanks in advance
