SubjectRe: Disk hardware caching, performance, and journalling
Date
I think if you have a large mail server and zero power protection, you've
got much larger problems to worry about than write-behind caching on your
disk drives... my servers have never (in my memory) experienced a
catastrophic power failure, because they're too easy to avoid.
