Both work very well. The PCIe NVMe is a recent development. The Sata version is in use for some time in tablets, notebooks etc. After dropping the system on the floor the housing is mostly cracked, but the SSD is still in a good condition. The limit of both is of course the max transfer speed for the USB3.1. Although the PCIe is capable for a much faster working speed..
There is not so much price difference. The PCIe NVM is already available with 128 GB for around € 19,- (Ali Expres).
On the RPI Pi 4 you must install the latest Eeprom and setting boot from a usb in the raspi-config
I'am waiting for some time of the CM4 system where the IO board has a PCIe slot. Then I can test the PCIe with its real speed.
The latest Argon housing with the M2 case has an addtional board with a slot for a sata SSD. it also shows full HDMi slots.
It works very well and fast.
And with SD copy application you can copy your SD to SSD or the other way around. If there is a problem you can simply switch to another storage device.
