I wonder if this is also due to the fact that many desktop SSDs do not focus on 4k read/write performance. This is one big area where nvme SSDs seem to have an advantage, their 4k read/write is usually significantly higher than that of other SSDs (at least from benchmarks I've seen). Maybe even a lower end nvme ssd + usb enclosure would be the way to go to get the best performance. Unless there's something about the USB interface itself that kills random 4k r/w performance?
