For arrays without a battery backed cache, write through configuration (i.e. read cache enabled, write cache disabled) is the usual safe default. You can alter your write cache settings using Doug Gilbert's sg3-utils ... but be warned, enabling the write cache without battery backing in an array is a dangerous thing to do since most arrays have huge caches, they either ignore SYNCHRONIZE CACHE (which would leave you vulnerable to data loss on power failure) or take such a long time, it would kill performance.
