Remember that the new Pi 4B has USB3, and according to the benchmark posted on their site it can read from an SSD over USB at 363 MB/s, and write at 323 MB/s. That's pretty good, I don't think you'll get much better than that with a SATA chip connected to the same SoC, so a regular external hard drive with USB3 is probably the best option for most Raspberry Pi customers. The Rock64Pro is probably a great board too, and it also has USB3, so it can do both options. There's some Odroid boards that have built in SATA as well. https://magpi.raspberrypi.org/articles/raspberry-pi-4-specs-benchmarks https://magpi.raspberrypi.org/articles/raspberry-pi-4-specs-...
