I can only assume you're referring to Intel's Rocket Lake storage demonstration they tweeted out. This was using PCMark 10's Quick Storage Benchmark which is more CPU bound than anything else.

All of the other benchmarks in the PCMark test suite push the bottleneck down to the storage device.

One would think Intel might want to build a storage array that could stress the PCIe lanes but then that might show an entirely different picture than the one Intel is portraying.
