Heh, I'd argue that ZFS would be better if they went with 64 bits, especially since it's 2^128 blocks, not bytes, or bits. I did the math and it was something

Heh, I'd argue that ZFS would be better if they went with 64 bits, especially since it's 2^128 blocks, not bytes, or bits.
I did the math and it was something like a decade of the worlds production of disks, in a single filesystem. I could somewhat understand if it was a distributed filesystem, but it's not.
- kstrauser 5y agoAccording to back-of-the-napkin math, my home NAS has more storage than was manufactured globally in the year I bought my first computer. It doesn’t seem impossible that someone might have a single pool too big for 2^64 by the end of ZFS’s useful life.
- scoopertrooper 5y agoI did some calculations of my own. Assuming a index of size 2^64 and a block size of 256 KB, you could store 6,949,999,424,954 hours of 4k REDCODE36 RAW 4K video @ 120 fps before you ran into problems.

- usr1106 5y agoThat's the way it has been in IT for 6 decades. The problem is it's not sustainable. We ruin the planet by inventing ever new ways of wasting resources for new solutions to problems that mankind doensn't even have.
