I was reading Absolute FreeBSD (good book)
and there was a mention that data is a lot safer
with disk write caching off. i.e.
hw.ata.wc=0
so i tried it and it turned my dual core AMD64 into an 8086
when I did any disk writes.
(I copied a 4G file from a USB disk to /usr)
the write took about 900s opposed to 227s
all my desktop slowed down as to become unusable.
so I turned it back on.
So, my question is do you think there is an appreciable increase
in danger of data loss?
i.e any one experienced it.
