I think he was referring to Amazon S3 prices which are up around the numbers he mentioned. But Amazon also has "Glacier" for 3/4 of one penny per month, and Backblaze has an S3 competitor for even less at 1/2 of one penny per month.
Disclosure: I work on Google Cloud (but not Nearline).
What do they have 300TB of, if it's not a rude question... ;-)
