Some years ago I realized that if I had oodles of money to spend I would totally get someone to make a PCIe card with like several hundreds microSD cards on it.

You can buy vertical microSD connectors, so you can stack quite a lot of them on a PCIe card. Then a beefy FPGA to present it as a NVMe device to the host.

Goal total capacity, as you can put 1TB cards in there. And for teh lulz of course.

This isn't a very difficult thing to build, but I am curious - what's the point? Who is the market?

The main point would be teh lulz as mentioned, and the market would be me. You know, just because it's possible.

Physically easy to build, main challenge for me would be FPGA implementation.
