		+	==Write Cache==
		+	There are (2) types of write cache, (1) on the drives and (1) on the controller. On the controller there is a read/write ratio which should be leaning more toward the write side, like a 25%/75% for optimal performance.<br>
		+	Optimally you need to have the battery installed on your cache module, however you can force it enabled, just keep in mind that anything on the cache during a power outage may result in corrupted file(s).
