I have a fairly large number of HGST "NAS" drives in service across
multiple locations (several dozens units total.)=C2=A0 I don't like their=
 5Tb
models much (they're slow comparatively for an unknown reason) but the
4Tb and 6Tb models I have in the field, while noisy and somewhat more
power-hungry (the latter comes from the 7200 rpm speed) have yet to
suffer a failure.
