There are only these three hddcompanies left: WD, Seagate and Toshiba.
Synology doesn't produce drives, they buy them from Toshiba.
If you want to know which drives are good have a look at the backblaze reports:

They still list HGST (Hitachi) drives separately. Hitachi was bought by WD more than 10 years ago.
