SSD Over-provisioning

I recently had to replace my SSD C-drive after getting a SMART alert on my Dell Windows 10 PC. I downloaded and ran the manufacturers drive manager software which confirmed the bad SMART status and said the drive had 9% life remaining. I cloned the old 256 GB SSD and replaced it with a new Samsun 500 GB SSD, and everything seems to be working perfectly.

I’ve been reading about over-provisioning and found that some over-provisioning is built in to SSDs. Some recommend that you should use the drive manufacturers software and make the over-provisioning be about 10% of the drive capacity. I don’t know if this is necessary or not and am hoping this knowledgeable group can give me some guidance on this question. Do you think the built-in over-provisioning is enough or should I change it to 10%?
