HGST Ultrastar DC HC520 12TB HUH721212ALE601

Building a Truenas setup and I have been reading up on the SMR/CMR drives. I have found these refurbished for $82/each and the seller is adding another 5 year warranty on them. Should I grab 2 of them?

I dont’s see them listed in the list I have,but the HUH721212ALE600 is on the list as CMR. I read that anything over 8TB is CMR anyways.

Here is a link to the WD datasheet. WD usually omits crucial details when they want to lie but this case / drive SKU is pretty clear cut.

The recording technology description “traditional perpendicular magnetic recording (PMR) technology” in the linked spec sheet is aka CMR.

I have had very good experiences with these helium-filled drives, which I have mostly bought renewed with a 5-year warranty from goharddrive.com. The latest batch was $79 ea.

16K Power on Hours as of now.

Just mind the 3.3V Power Disable feature on Ultrastar drives: Power these through a backplane or 4-pin Molex.
