>Just like DDR3 has the lowest CAS latency with ok bandwidth and longevity.

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.

>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!

What's the point of it lasting 100 years if it's terribly out of date?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.
