We don't actually know the % of how much bandwidth of the SSD was being used on the Playstation 5.
For all we know it was only 500MB/s and a Sata SSD is more than enough to handle it.

However the Unreal Engine 5 demo is entirely capable of running on the PC... And capable of running better than the Playstation 5, the PC can push higher resolutions, framerates and effects.
And on the SSD front... The Samsung 980Pro SSD for instance can do 6.5GB/s which will be out before the PS5 releases and doesn't use TLC or QLC NAND either, but MLC... With a controller that has a chunky DRAM cache.

Good thing we're not talking about the SSD alone then but how it's integrated in the system's architecture. Or, to quote Tim Sweeney: "The storage architecture on the PS5 is far ahead of anything you can buy on PC for any amount of money right now. It’s going to help drive future PCs."

Btw, I'm pretty sure we'll be able to upgrade to an even faster SSD in the future as prices come down.

Also, @bolded: Why didn't Epic show it running on PC like they did in the past for their previous engines? If I'm showing my product I would want to show it in the best light possible.

Could be a variety of reasons. There could be some financial benefits put in place or development/technology sharing in order to gain more developer support for the engine, who knows.
EPIC follows the cash cows typically, hence the Epic Store, Hence why they partnered up with Microsoft once, hence why they dropped the Unreal Tournament sequel in favor of Fortnite. EPIC is a business, it's capitalism at work.

We don't know if the drive is upgradeable in the Playstation 5, it's not a commodity drive, so they may lock it down to ensure a degree of consistency with the performance, they wouldn't want people replacing it with a drive half the speed, would they?

But let's say that it theoretically was capable of being upgraded... It would be limited by the 4x PCI-E 4.0 lanes... Which tops out at 8GB/s. (Actually less in the real world due to overheads and so forth.)

Where-as PCI-E 5.0 is gaining traction in the PC space (Controllers already exist) which would offer 16GB/s on a typical nVME drive with 4x lanes.
Or get a PCI-E addon card with 16x lanes for a total of 64GB/s.
