You would think that, but I also have Samsungs industrial 3.5TB drives and they are flaky at best.
Eternal growth does not exist, SSDs peaked in 2011 for durability without complexity.
Just like DDR3 has the lowest CAS latency with ok bandwidth and longevity.
DDR4 actually breaks after 10 years.
DDR2 probably lasts more than 100 years.
Think about that, any device manufactured in the coming 50 years will be outlived by 32-bit Raspberry 2!
You just need a bunch of older SD cards and distributed storage so that you don't loose data.

Source? AFAIK successive generations eventually had the same or slightly CAS latency in absolute terms. However, because CAS latency is measured in clock cycles, and successive generations have higher clock speeds, the latency "number" is higher, but that's an illusion. DDR3-1600 CL8 has the same latency as DDR4-3200 CL16.

What's the point of it lasting 100 years if it's terribly out of date? An IDE drive from the 2000s is basically unusable today, 20 years later. CPU from around the same era is basically on its last legs because software support is being dropped[1]. Your SSDs are going to suffer the same fate. And that's not even factoring in other considerations like power consumption, and the hassle of trying to connect 30 drives to a computer.

As you increase Hz you increase energy and then your components fail faster.
The point is "the 1000 hour computer" = we are going into rent seeking hardware.
I'm obviously not going to use 30 SSDs in one computer.
You can google "perma computing" if really want to binge.
I don't use SSDs, but the HDDs in my NAS started failing one by one after a few years. Whenever one failed, I just put a new one in, and that was it. ZFS rebalanced things automatically and I went on with my life.
It just sounds like you spent $3k to solve a problem you could have solved with $200...
Unrelatedly, does the name "Realms of Despair" mean anything to you?
HDDs make noise, you can only use them if you have more rooms than you need.
Nope
Everyone has a closet or cupboard under the stairs where a NAS can live. it doesnt need a room of its own.
But my argument was "a failing disk can just be swapped for another one with zero other hassle".
