HFS+ Filesystem Repeatedly Corrupting

Question

I have a 5TB external HDD that I've been using for about 2 years reliably. I primarily use it attached to either a raspberry pi or Synology NAS.

Recently I've noticed a lot of corrupt files and when running fsck.hfsplus -f I get a whole host of issues (not the same issues every time either). Usually fsck will repair the disk, but occasionally fsck will fail and I will have to run DiskWarrior on it and rebuild the catalogue. The corruption seems to happen very shortly after repairing the drive and seems to be somehow related to write processes (when I leave the drive alone without writing it take a lot longer to break).

Is this drive toast? I ran an extended SMART check on it and it came back completely fine. Should I try dding a copy of this disk to another drive, wiping the drive completely and dding it back? Any help is appreciated!

Here is an example of one fsck output for reference:
