I have unlimited photo storage on Amazon photos, unlimited video storage on Google photos and unlimited anything with Google onedrive.

Amazon gives you free access to Amazon photos if you have prime - 82% of US homes have a prime account (150 Million)

Google says 1.2 billion photos are uploaded every day to Google photos

There are apparently 20 million Onedrive accounts out there with unlimited storage or at least 1 TB

The World Economic Forum estimates that this year, the size of the digital universe could hit 44 zettabytes. That sum is 40 times more bytes than the number of stars in the observable universe. And by 2025, projects are that this number could nearly double.

Ask a silly question and here is the answer according to wickipedia

The zettabyte is a multiple of the unit byte for digital information. The prefix zetta indicates multiplication by the seventh power of 1000 or 10²¹ in the International System of Units (SI). A zettabyte is one sextillion (one long scale trilliard) bytes.^{[1][2][3][4][5]} The unit symbol is ZB.

1 ZB = 1000⁷bytes = 10²¹bytes = 1000000000000000000000bytes = 1000exabytes = 1millionpetabytes = 1billionterabytes = 1trilliongigabytes.

1000 ZB = 1 yottabyte (YB).

A related unit, the zebibyte (ZiB), using a binary prefix, is equal to 1024⁷ (=2⁷⁰) bytes (approximately 1.181 ZB).
