I'll add - drives from different brands. I had a mirrored RAID 1 fail at one point (in the '00s, spinning magnetic hard drives), two identical drives, and they failed within days of each other. One drive died, I ordered a replacement, and before the replacement arrived the second drive died. The shock and disbelief I felt of my foolproof RAID solution going belly-up on me! And I still can't believe I didn't turn off the machine while I waited for the replacement to arrive.
