Testing Drives In New System Without OS

I bought some SAS drives from BitDeals for use in a new Unraid server. I’m going to migrate from a Windows server, Synology, TrueNas and Xpenology onto Unraid, and this server can run SAS 12g with a Dell HBA330 I flashed.

For this blank system, what would the best way to get SMART and stress-test the SAS drives prior to putting data onto them? Is there an easy option in Unraid? I’ve seen some scripts put out that haven’t been updated since 2014.
