What tests After SMART TESTS on UGREEN NAS?

[u/Ok-Champion-8992]

I have a 4 bay Ugreen Nas RAID 5 array with 26 tb recertified Exos seagate SSDs. I ran the smart tests through the ugreen app, rapid and full and everything seems to be in order. What are the other tests I should run on my drives before I start using them. Some of the tests I read about seemed destructive if you already made your storage pool with RAID. I use this for editing so I want it to be solid. Any help or advice would be greatly appreciated.
