Re: OpenBSD and FS-Support (compiling kernel without support..)

You missed the point, in-controller write caching could cause data
loss during a power fault, if the OS is doing appropriate
checkpointing of the data, you really don't want the disk trying to
be clever too.

In reality, yes, if you're worried enough to turn off write caching,
you'd be mad to not have a UPS - if only to condition your power to
prevent a spike frying the drive controller electronics.

They sell UPSs that stop OpenBSD from crashing now?  What's the pricing like
on those?
