I can't remember where I saw it, but I think each of these high capacity drives is in well into the 15-25k price range.

So a petabyte will be $600-800k alone, plus a server with enough high-speed PCIe lanes to serve the 40+ drives, definitely $1m+

They are likely 200USD+ per TB, so one 250TB drive would be ~50,000USD.

There’s probably bulk pricing, but if you bought 40 drives separately thats 2,000,000USD in storage alone.

$500 on Facebook Marketplace in 20 years time.

More than you can afford cause you had to ask, ha

You can't buy this stuff anymore. They are leased and rented through layers of middlemen.
