I was using a Pi 4 for a NAS. The Pi started dropping connections to the SSDs when using a 4-port external powered usb 3.0 hub. Apparently the Pi could not handle potentially conflicting USB IDs of the SSDs and the hub when the last port was filled. The HP EliteDesk 800 G2 has no problems at all with this, runs MUCH faster and just as cool as the Pi with the same version of Linux for not much more $ than a Pi 4. Very happy with the swap.
