[OmniOS-discuss] HGST HUS724030ALS640 vs WD WD4001FYYG

[Tobias Oetiker]

We are looking into buying some new 4TB drives for our omnios ZFS
boxes. The race is between these two devices ... both sas, both
512n both 4T.

  HGST HUS724030ALS640 vs WD WD4001FYYG

I have heard anectotal evidence that the WD Re drives were
much more preformant than the HGST offering.

   20 MB/s (HGST) vs 140 MB/s (WD Re) scrub performance in a Mirror setup

We are using the HGST devices at the moment and they did not feel
especially nimble ...

can anyone share their experiance ?

cheers
tobi
