Hello, today after the automatic update to this version (.80), one of the two drives in the mirrored RAID array on a supported NVMe drive (a Kingston KC3000) crashed.
I haven't resolved the issue yet. Everything was fine before. The F8 SSD Plus didn't make any noise.

I updated all three of my devices via the mobile app, all updated w/o issues. It was more of convivence this morning to do it that way.

how often does TOS check for new updates? i have mine set to email me but so far i haven’t received an email to tell me a new version is available

after the installation i do get the email from both my NAS's to tell me its installed / rebooted etc so i know its set up correctly to email me
