A.
Because an SSD is itself a memory device, Dell recommends disabling write cache for all volumes using SSDs to maximize performance for most applications. Disabling read cache for volumes using SSDs is application-specific and may or may not improve performance. Dell recommends testing applications prior to disabling read cache.
