If your cache is backed by a battery, enabling write cache shouldn't
be a problem. You can check if the whole thing is working well by
running this test script: <http://brad.livejournal.com/2116715.html>
Enabling write cache leads to various degrees of data corruption in
case of a power outage (possibly including file system corruption
requiring manual recover).
