I decided to do a quick 'dd test' of my home-made USB attached m.2 NVME drive and with a 1MB block size was able to get over 800MB/sec sequential read performance from the /dev/sda device. That is substantially faster than a SATA III interface can even theoretically provide plus essentially zero seek times compared to rust. Even an internal SATA based SSD would seem to be at a disadvantage. While I was playing with it, I went ahead and installed VenToy on it and tried booting a few Linux ISOs. It certainly felt plenty fast on the Core i5 6200U based laptop I was using for testing.
