> 16 million terablocks, or 8 billion terabytes.

To be clear, the first quote was talking about 2^64 bytes, and you're talking about 2^64 blocks.

Edit: Though confusingly the second part talked about 2^128 blocks.

Also these days I'd assume 4KB blocks instead of 512 bytes.

That's 16 exabytes. Wikipedia cites a re:invent video to say that Amazon S3 has "100s of exabytes" in it.

So it not only could theoretically be done, but has been done.

For the record, 44TB drives have been announced in March 2026:

SSDs have outclassed hard drives in density for a while now. Kioxia claims their LC9 is over 245TB in capacity, announced July 2025.

How much does one 245T LC9 cost, and much much do (245T÷44T=5.5=) six Seagates cost?

I have a bunch of NVMe enclosures that generate 750W of heat when going full blast, and 600W when completely idle. How heat does the equivalent number of HDDs generate when working/idle?
