What do you guys do with your old SSD after cloning?

I just cloned everything over to a new SSD. Do you usually keep the old SSD around for a while in case something goes wrong, or just wipe it once you know the new drive is working fine?

I was thinking about putting it in a USB enclosure and using it as an external drive. What do you guys usually do with the old drive? Keep it, reuse it, sell it, or just leave it in a drawer?
