This is simply not true. ZFS would protect against the same type of errors seen on an individual drive as it would on a pool made of HW raid LUN(s). It might be overkill to layer ZFS on top of a LUN that is already protected in some way by the devices internal RAID code but it does not "make your data susceptible to HW errors caused by the storage subsystem's RAID algorithm, and slow down the I/O".
& Roch's recommendation to leave at least 1 layer of redundancy to ZFS allows the extension of ZFS's own redundancy features for some truely remarkable data reliability. Perhaps, the question should be how one could mix them to get the best of both worlds instead of going to either extreme.
True, ZFS can't manage past the LUN into the array. Guess what? ZFS can't get past the disk drive firmware either....and thats a good thing for all parties involved.
