Updated replacement model for VelociRaptor

Have a 9 year old 150GB VelociRaptor HD model WD1500HLFS that has a “hot swappable” connection for data transfer and power. Looking to upgrade to newer model with larger storage capacity (4T).Reviewing the various drive models, specs and photo’s I’m unable to discern which WD version is the appropriate replacement model and provides the correct type of connection for my system. Any thoughts or pointers in the right direction would be most helpful. BTW, I don’t use or need a drive for a RAID configuration.
