smr drives are just slower at writing, otherwise just as reliable ... for storing movies music and even games they're fine

the first image says it could be either, but then the second image states that only WD Blue 2tb and 6tb are SMR and all other are CMR(read the note at the bottom)

No, the second picture says  AT THE DATE OF 6th OF JULY , those models in the picture were IN PRODUCTION.

 

It doesn't say if a week before that document they still made 4 TB WD Blue drives with SMR, or if a week from that day, they started making WD Blue with SMR again. 

 

There was a 4 TB WD Blue with SMR made before, and since there's no guarantee you will order a drive and get a drive manufacturer AFTER the 6th of July 2020, you can flip a coin and have about the same chance of guessing the correct answer.

 

The only guaranteed CRM drives from WD are the 8 TB and above, the WD Black and Purple, and the 1 TB drives (makes no sense for SMR on such drives because they can probably store around 700 GB per side of platter).

Here is the model number for 4tb WD Blue CMR HDD WD40EZRZ. 

 

at least i can confirm wd.....AZ is smr with 256mb cache, while RZ has 64mb cache but its crm

 

the sales person took the wrong model to me, luckily i refunded the AZ smr

ive got a bunch of 8tb seagate smr hdds and they work perfectly fine.

if you're worried about performance you could get some cheap ssds and use them as cache drives

 

you can do that with Storage Spaces in windows 10 pro, see here and here. it works great for me
