Are Any of These WD USB External Drives Worth the $?

None of OP's drives were SSDs?

For hard drives, this is still on the order of years before you'll get an uncorrectable error (on average).
You should still spin disks up periodically for mechanical reasons, but unless you're using properly configured ZFS, I'm not aware of any file system that actively scrubs for bit rot.
In SSDs, the controller will shuffle data around when powered-on as the cells weaken, but an equivalent for HDDs would be overly-cautious at best and downright abusive at worst. HDDs will reallocate sectors that initially fail to read but then are read successfully, but this is done reactively, not proactively. If the sector fails unrecoverably before being read, there's nothing the HDD will/can do.

See here for a price/TB breakdown of a wide array (heh) of available drives.
