I agree that if you ran a synthetic benchmark against a brand new pure x20 with 10 NVME drives you'd see astronomical numbers for iops.
That is absolutely not representative of a real workload of mixed reads and writes, different block sizes, potentially different queue depths, all coming in on hundreds or maybe thousands of different volumes.
A single consumer Samsung SSD would hilariously crumble under a real workload, it will NOT deliver hundreds of thousands of IOPs in that environment.
Your benchmark screenshot is the equivalent of showing your pickup truck can do burnouts in the parking lot, and extrapolating that to think it could keep up with a Ferrari on the Nurburgring.

if you see bottleneck there, it could be that actual SSD speed is maybe irrelevant in your case since upstream software is not optimized.
