Only way to find out is to buy one and discover it's got poor write speeds, apparently. I ended up buying a manufacturer refurbished 10 TB Gold datacenter drive for $170 on eBay to replace it, because I was certain it was PMR (was right in the description). PMR - Perpendicular Magnetic Recording (both CMR and SMR type drives use it). WD knows exactly what they’re selling, naturally. In fact they use the technology on mainstream devices like boot drives. I have DOZENS of them, mostly external! They wouldn’t replace it because I took it out of a MyBook enclosure. The Gui showed my about ~125MB/s for each disk. Hard drives were already bad at random access I/O—but SMR disks are worse. All rights reserved. AND GET THIS! 6 months ago. FYI, the 10TB uses a similar WD100EMAZ helium drive.

PMR is the successor to Longitudinal Magnetic Recording (LMR) and achieves a data density three times higher than its predecessor LMR – the read / write head has been optimized for this and the vertical positioning also contributes to this. It seems like a marketing TEST!!! The popularity of Network-Attached Storage (NAS) systems has fuelled a surge in demand for large capacity hard disk drives. 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 because certain drives earmarked for use in NAS were not really living up to the performance expected. Paste it to a text editor, and voila!!! https://support-en.wd.com/app/answers/detail/a_id/20230. PMR/CMR, perpendicular/conventional, are essentially the same thing these days. Also fine.

The second “technician” said SMR stands for Standard Metabolic Rate! It works great, but I'm a little bit uncertain whether the write/read are slower than they should be.

More power than that in the radio brings no benefit, except if the radio is used in DMO. Now HGST has taken their helium technology and expanded capacity even further with the Ultrastar Helium He8 8TB … Using SMR technology instead of conventional magnetic recording allows HDD manufacturers to put out denser drives at cheaper prices. Therefore, it's possible you didn't get a drive using SMR depending on when you purchased it.
