If that is what you want to do, yes you can do that. Still, is a raid5 a good performance/safety decision?

__ppc_mdoio
__PPC_YIELD(3) Linux Programmer'sManual __PPC_YIELD(3)
NAME
__ppc_yield, __ppc_mdoio, __ppc_mdoom - Hint the processor to release shared resources
SYNOPSIS
#include <sys/platform/ppc.h>
void __ppc_yield(void);
void __ppc_mdoio(void);
void __ppc_mdoom(void);
DESCRIPTION
These functions provide hints about the usage of resources that are shared with other processors on the Power architecture. They can be
used, for example, if a program waiting on a lock intends to divert the shared resources to be used by other processors.
__ppc_yield() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are
released for use by other processors.
__ppc_mdoio() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are
released until all outstanding storage accesses to caching-inhibited storage have been completed.
__ppc_mdoom() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are
released until all outstanding storage accesses to cacheable storage for which the data is not in the cache have been completed.
VERSIONS
These functions first appeared in glibc in version 2.18.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
