But I remember using tape drives like these:

Me too, Your picture is an IBM 727 ~ early 60's, I used those in the late 60's. I worked on the next
generation competing with the IBM 3400 series. One tape controller (all the electronics except the tape
drive servos) could control eight ( if I remember correctly). Roughly $50K for the controller and eight
drives at $15K each in 1970. More than $600K in today's dollars for a max of l.5 GBytes on line with
a worst case access time of 60 seconds. But in reality most systems were not bought they were leased
and came with an onsite customer engineer to minimize down time. As we all recognize we have come a
long way.

I have SSD plus a RAID 5 redundant hard disk system at home with still another drive for weekly backup.
Have used RAID systems on multiple system upgrades over the last 20+ years and in that time I can only
remember two drives fail. Never any down time just replaced the bad drive and continue playing.
