I just want to know if the following is possible:

- Verify if RAID1 works properly on this product (make sure it’s writing on both drives)
- Check SMART status of each drive (already tried smartctl, result below but doesn’t look like it’s successful)

I installed two 4TB IronWolf HDD on RAID1 config, then connected it to my mini PC USB 3.0 (running ubuntu). So far it works as expected of an external USB drive.

smartctl result:

I’m planning to use this a backup and media drive and would like to be sure if my files would be safe.

Please help. TIA
