The intern HDDs of my PCs did last for around 2 years, when turning the computer off and on several times a day and they did last for around 7 years, if the machine runs more or less 24/7. > A few year ago Western Digital made some green drives, with extremely > aggressive power saving, that parked within seconds.

I'm the owner of such an external green WD drive. It does park the heads and if people aren't careful right after parking something like gvfs or smartd etc. does wake up the drive immediately, for absolutely no reasons. There probably were a few drives where this happened every few seconds, but more common is, that it happens after around 30 minutes, which already is way to often. If you remove gvfs, don't enable smartd etc. those green drives get very old. Mine already is very old and still alive. It should be years older than this dummy package, I build in 2013 to fulfill idiotic hard dependencies against gvfs.

All inexpensive TiB drives are SMR drives. There's no data sheet needed. If the drive is inexpensive, then it must be a SMR drive. Btw. I'm using a lot of external, inexpensive "Toshiba P300 - Desktop" drives.
