Enable write back cache on RAID 5 good idea or bad idea
Posted on 2011-09-12
I just installed Intel Rapid Storage Technology and can now see what the heck I have been missing all this time. Wow. Server has been running with no way to monitor the condition of the drives. Now that I have this Intel utility running, the first question that comes to mind, if I enable the volume write back cache, is that good, bad? What is typically done? This server has been running with that off, so I am thinking it will improve our wait time on SQL queries? It is connected to a UPS with about a 2 hour run time, so I don't think power interruption is an issue. Any other considerations before I decide to turn it on?
