I'd be interested if one of the various hacks for PCIe ( https://hackaday.com/2019/07/10/giving-the-pi-4-pci-express/ ) to plug it in natively would work and, if yes, at what speed.

Afaik its limited to 3 gigabyte per second, so just plugging it into the usb 3 port should give the same speed.

This is just plugging in NVMe over the USB 3 port? I was expecting this to be soldering something to PCIe lanes coming out of the SoC.

Is this going to be any better than using an SSD with UAS which is what I'm doing already? (https://rwmj.wordpress.com/2020/09/24/raspberry-pi-4-running...)

These sorts of posts come up often and I cringe every time I see dongle attached storage. An unnecessary additional failure point seems counterproductive.

I have a Raspberry Pi and I use an SD card because what I’m using it for doesn’t require anything more. If you need fast storage I believe you should buy an appropriate device and maybe petition the Foundation to add it in a future model.

Right tool for the job and all that.

One of the leading reasons for using USB attached storage on the Pi is to avoid SD card corruption issues.

FWIW I have not had any SD corruption issues after 1) using name-branded cards and 2) ensuring that I feed each Pi w/5.2V. In the end I bought a commercial 5V power supply, tweaked it up 5% and wired directly to the 5V pins on the Pi.

You can get the same corruption on ssds if power draw is more then pi allows or if power goes down.

With an SSD you are increasing power consumption on USB which is limited to around 1.2A or however much power supply allows.

Note: I havent had any corruptions past year on pi3... all I changed was power supply, sd card and using aarch64
