snip

They are moving to SSD drives for boot drives. They published the
Lifetime failure rates. 8 out of the 1,518 SSD boot drives failed
(0.65%). 559 out of the 1,669 hard boot drives failed (6.04%).


It seems that I've forgotten how to calculate percentages.

8 out of 1518 appears to be about 0.52%, versus 0.65%

559 out of 1669 appears to be about 33.5%, versus 6.04%

I guess I should go read the article to see how they calculate that.


The percentages take time into account.
