[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?
