I've lost a 3T collection of HDTV movies back in the day (student) because of WD green drive that decided to return something else that was written to it in a USB box. Took me a while to realize what's going on, but seeing cksum errors when this particular drive was a member of zraid1, I didn't lose any more data (blocks with correct data and checksum were returned from pool) and was able to replace it on my schedule and money. Since then, I just don't feel like gambling on bitrot. Neither on movies, nor on family photos.
