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.
Running 6 of these without any issues.
Model Family: HGST Ultrastar He10
Device Model: HGST HUH721010ALE604
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.
The Power Disable feature is not available on all HC520 right? I’m eye balling some recertified drives and I can see both of the drives I want to purchase are leballed as HUH721212ALE600, one of them is 0F30144 and the other one is 0F29618 (that has the Power Disable feature).
No, but I’ve seen it on most. It’s in the product code—the ‘L’ if I remember correctly.
I think the “L” is supposed to be the dimension according to:
I’m still unable to find much info about the “Power Disable” feature.
