is zfs any less efficient with just using a portion of a

As others mentioned, if we're given a whole disk (i.e. no slice
is specified) then we can safely enable the write cache.
With all of the talk about performance problems due to
ZFS doing a sync to force the drives to commit to data
being on disk, how much of a benefit is this - especially
for NFS?
Also, if I was lucky enough to have a working prestoserv
card around, would ZFS be able to take advantage of
that at all?
