Looks like most of those also have coupons OP, so prices are actually lower than in your post Wink for all but the 2TB drive.
Thanks, updated post.

Reminder that all of these drives (minus the 8TB model) were recently exposed to possibly be SMR (shingled magnetic recording). Not that they are bad drives, but I personally would not want to use SMR drives in any RAID configuration. WD finally came clean after the blow back from the tech community. For details I would look at servethehome.com coverage about it.

Interesting info. Relieved I got a non-SMR WD40EFRX when I ordered from Western Digital directly back in December.

Ummm good luck finding any 2TB - 6TB drives that doesn't use SMR. Seagate and Toshiba both use it.

The 1-6TB models in the scroll list with 64mb cache are CMRs, while those
with 256mb cache will be SMRs.

The SMR drives are actually called xxxxEFAX, instead of xxxxEFRX, but
B&H didn't write out the model.

Seagate currently don't use SMR in their NAS disks (see last link).

Understand that it might be tough to find non-SMR drives in that size range. But I would prefer to at least know what I am buying. Also these are being marketed as "NAS" drives. If I had a RAID application, I would really look to pinch some pennies else where and get a larger non-SMR drive. But ultimately it is up to the buyers risk tolerance. Just wanted to inform folks so that they can make that decision themselves.

The information on the site for the 4TB reflects these are the 64MB cache. The model number on the photo included on the B&H reflect the EFRX model. The UPC on the bottom of the page coincides with the EFRX model on Amazon.

Checking this link, from WD, verifies that the EFAX model is the SMR drive.

Hope that helps everyone.

So EFRX = non-smr.
EFAX = smr.

Hmm, tempting.

So.... are these SMR or not?
Depends on which one you choose in the list of available drives at B&H.

less than 8TB and 256mb cache = SMR.
