WD40EFRX CMR or SMR?

Hi there!
I’m looking for some help with understanding which drive to buy to replace my damaged WD40EFRX. Can anyone tell if this model is CMR or SMR? If it is SMR and I replace it with a CMR model, would the remaining SMR drive be compatible?

Models currently available in Brazil are different from the ones in the US and I can find the EFRX models here, but some of them are labeled as Red instead of Red Plus.
Thanks for your time!
