It's A Digital Disease!

I have three 4TB drives and I need some redundancy for data protection. However while researching the topic I found out many people avoid RAID5 due to very long rebuild time ("your second drive will fail before rebuild finishes").

But the estimate numbers I found online contradict this, sort of, stating that rebuild time for RAID5 usually ranges from 24 to 36 hours. How is that possible that the two drives fail in a single day? Has anyone ever lost data to this scenario or this is just a hypothetical boogieman?

Drives are expensive where I live.
