G-RAID 20TB-M1 MacBook Pro: test integrity and update firmware?


I have a thunderbolt 2 G-RAID 20TB Drive configured as Raid 1 to mirror my photograph library. After multiple hard disk failures on other drives (edit for clarity other manufacturers, not my G-RAID), I’m about to invest in a new thunderbolt 3 version.
I want to check the status of my current drive (about 4-5 yrs old) and having spoken to my supplier I downloaded the G-RAID with Thunderbolt Configurator.

However when I run the app, it doesn’t give me an option to check configuration, or update firmware, just ‘Configure’. I don’t want to do that until I’ve backed up onto my new drive as I’m worried that configuring the drive may also erase the data.

I can see a big green tick, which I presume is telling me both disks are healthy. Is there any other utility I can run to check disk integrity? And, is it possible to check to see if firmware needs updated without pressing configure? (you can see the firmware number in the screenshot).
