SMR or SSD disks?

Hi guys
i'm doing some maintenance replacing some not-yet-failed HDD with WD RED SSD.
I've read the warning on the homepage
https://raid.wiki.kernel.org/index.php/Linux_Raid

Are SSD drives still subject to SMR ? I've thought that it was related
only to magnetic drives not on SSD.

in example i have a WDC  WDS200T1R0A (WD RED SA500), is this subject
to SMR and I have to replace it anyway ? (i've added it to the raid
right now, moving from a 2 way mirror to a 3 way mirror)

If I have to replace them, which 2TB SSD should I use ? Usually i've
used Samsung SSD but i've read some bad reviews on newer models.

Any suggestions ? Ideas ?
