That's great that you have that cache memory but it ends up being entirely unused for writes as you run in writethrough mode. Writes are the slow ops reads are significantly faster so by running in write through mode you're unnceessarily compromising the performance of your array. Most RAID controllers with battery backup are good for 3+ days of backup if you're so concerned about being power free for longer than that I suggest you need a generator my friend.
