I removed WD from our preferred suppliers list unless it’s used material - which then goes into something else - suited for refurb material. Some 8’s are SMR, but mostly PMR, and as far as I can tell, most 10 TB drives are SMR. From what I read, they started inserting SMR drives into the red NAS line around early 2017. No response on that. DM-SMR - Device Managed Shingled Magnetic Recording. You can refer the link provided below for more information on PMR technology. So they can target “specific” markets with the SMR drives? Now HGST has taken their helium technology and expanded capacity even further with the Ultrastar Helium He8 8TB … The popularity of Network-Attached Storage (NAS) systems has fuelled a surge in demand for large capacity hard disk drives. WesternDigital continues to “hide” what technology is used in your hard disk. And after some coaxing, said that they are both PMR, but that doesn’t make sense because of the weight of the drives and their buffer sizes. This is a helium-filled 256MB cache drive, like the WD Red 10TB solution. Unhelpful (2) They are conventional PMR drives with NAS firmware.

The second “technician” said SMR stands for Standard Metabolic Rate! So, if anyone needs to know WHAT INTERNAL DRIVE MODEL they have in their WD EXTERNAL ENCLOSURES, install and COPY PAST the info to the clipboard! The PMR space is like temp work space that is written to at normal drive speed and slowly written to the SMR areas after. Prices and offers are subject to change.
