I found the options explaint in https://docs.broadcom.com/doc/12352476
[WT|WB] Write through / Write back
[NORA|RA] No read ahead / Read ahead
[Direct|Cached] Sets the logical drive cache policy
[CachedBadBBU|NoCachedBadBBU] Enables caching when BBU is not functioning
So I would say:
storcli -CfgEachDskRaid0 WT RA direct nocachedbadbbu -a0
is the best for use with mdadm?
