The cost of 12,400TB of storage is on the order of $100,000. UC Berkeley has an annual budget of over $3,000,000,000, i.e. this is 0.003% of their annual budget. Also, it's Berkeley, they probably have that kind of hardware sitting around. They should just stop using Google services.

You're grossly underestimating the cost. With some amount of redundancy and growth that would be 24TB of drive capacity at least. You're looking at $250k in drives alone. You also need almost 100 servers to host that many drives, so another $250k. Then they'd have to pay maybe $500k/yr for three sysadmins (including benefits). Then some amount for tape backups, connectivity, electricity, maintenance.

Perhaps still peanuts for UC Berkeley and worth it, I don't know, but it's not just writing a 100k check.

16TB drives are available for ~$150:

12,400TB is 775 16TB drives. Add 20% for redundancy and this is 930. At $155 this is <$150,000, not $250,000, and this is the primary expense.

> You also need almost 100 servers to host that many drives

No you don't, you put them in an array container, which will hold 24-48 drives, e.g.:

Those hold 48 drives, so you'd need 20 of them and they're ~$300. It doesn't even move the needle.

Why on earth would you need three sysadmins? After the initial setup this is a part time job for one person, and you probably already have that person because they're the ones dealing with all the problems caused by unreliable cloud vendors and forced SaaS software changes.

Tape is cheap. Universities already have fiber. Maintenance contracts are for bureaucrats, you just use commodity parts and then keep a few spares. Electricity is going to be some tens of thousands of dollars a year. This is all still "on the order of $100,000", i.e. the price has that number of significant figures. Then annual cost is actually less because the drives etc. will last for more than a year.
