Why is my Raspberry Pi 4 too slow as a server?

When you add up the component costs for RPi with NVMe, suitable case, cooling and power supply, it is not much cheaper than a mini PC which generally outperforms the RPi.

I use several RPis of various models. But there are times when even an old Intel/AMD laptop is a more suitable solution.

An old laptop has a built in UPS too!

a UPS has a battery that is safe under failure, a laptop usually doesn't.

> So I can read from my disk at 117 MB/s. We’re far from the theoretical 1000 MB/s.

I think you are confusing megabytes a second and megabit. Gigabit speed is approximately 125 Megabytes per second. This is close to the speed you got.

Yes but not there, later they get 350MB/s with the same setup.

> I put that drive an ICY BOX IB-1817M-C31 enclosure, with a maximum theoretical speed of 1000 MB/s.

Checks out, it has a 10Gb/s USB port.

The mistake is

> the USB controller of the Pi has a bandwidth of 4GB/s shared across all 4 ports

It's actually 4Gb/s = 512MB/s
