I can post pictures too.
Homework for you. Find 10 differences between that two pictures.
Well for starters, from both images.
PS5: Storage -> I/O -> Unified Memory. (Not using the GPU but dedicated hardware.)
PC: Storage -> GPU -> GPU Memory. (Uses GPU for decompression)
Nvidia says that RTX IO is a “suite of technologies that enable rapid GPU-based loading and game asset decompression, accelerating I/O performance by up to 100x over traditional hard drives and storage APIs.”
What is Nvidia RTX IO? A quick primer
When used with Microsoft’s new DirectStorage for Windows API, RTX IO offloads dozens of CPU cores’ worth of work to your GeForce RTX GPU, improving frame rates, enabling near-instantaneous game loading, and opening the door to a new era of large, incredibly detailed open world games.

I tried to find if there is dedicated hardware in the RTX GPU, so far no luck.
While on the PS5 the I/O does all the decompression work, thus freeing up both the CPU and GPU to do other work.
Maybe you should do your homework properly.

"So to solve all of that we built a lot of custom hardware namely a custom flash controller and a number of custom units in our main chip, (a pretty hefty unit dedicated to I/O) designed for smooth and bottleneck free operations"
