I’ve long wanted to build a small device that I could use to transfer files off of my camera’s memory cards while I’m out and about while traveling, as well as function as a small “travel NAS” when I am back at the hotel.
The Raspberry Pi 4 and its predecessors were too slow by way of read/write speed to make this practical, and the small Intel/AMD boards draw too much power.
The Pi 5 has NVMe support, and the reviews I’ve read indicate that using the CM5 with a carrier board it can achieve 700MBps read/write.
However, I’m curious what the implications would be of having to read from a USB drive (card reader, external drive, whatever) and write to the NVMe drive in the Pi. I can’t suss out whether or not there would be a bandwidth/compute limitation that would prevent me from saturating the PI’s USB3 interface while also writing to the NVMe drive…
