What a terrible article.
"We had one drive failure... Everyone take out the pitchforks!"
Yeah no. Drive failures happen. Period. https://www.backblaze.com/blog/backblaze-drive-stats-for-q1-2023/
I understand that there was a firmware failure in the 4TB drives... but come on, there's no journalistic integrity here to even CHECK what firmware the device was on? Nothing at all here substantial.
Further, you should be practicing 3-2-1 backups if the data is that important. It shouldn't matter to you that one storage failed.
