Re: TOS 7.0.0780 (X86) is Released for Update
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.
