I think they are reading it correctly. Year 1, they touched one drive and left 9 untouched. Year 2, they read one additional drive and left 8 untouched. Etc.

What do you think I am I reading incorrectly? The post seems pretty clear:

"I filled 10 32-GB Kingston flash drives with pseudo-random data."

"The years where I'll first touch a new drive (assuming no errors) are: 1, 2, 3, 4, 6, 8, 11, 15, 20, 27"

And from the blog: "Q: You know you powered the drive by reading it, right? A: Yes, that’s why I wrote 10 drives to begin with. We want to see how something works if left unpowered for 1 year, 2 years, etc."
