Pi400 boot from Flash drive / ssd: what works, what doesn't

Sat Apr 10, 2021 11:04 pm

So far I have found:

:D Kingston DataTraveler 100 G3 32Gb - boots from image written by RPi imager (Pi OS lite, Pi OS desktop, haven't tried Pi OS Full) (also tried RISC OS Pi and got as far as a command prompt, I got stuck!!).

:( Netac Portable SSD ZX 250Gb (UASP supported) - DOESN'T boot from either image written by RPi imager (Pi OS Full) or SD card copied using SD Card Copier (I suspect ticking the New Partition UUIDs option wouldn't do much)! The drive itself isn't bad, it's a LOT faster than the Kingston flashdrive and will still be useful.

Please add to this list (in the making).

type: USB vendor: Samsung model: PSSD T7 size: 500 GiB

Boots and works great on my pi400. All I did was use disk copier to copy my install from 64GB sd card to the SSD.

It is technically a Portable SSD. The drive itself has a USB-C port.

Netac Portable SSD ZX 250Gb
USB 3.2/USB C - the USB C socket is only wired for power supply.

(There are many threads on here about various USB disks, & usually on those that don't work, it is the adapters chip at fault.)

Every single pendrive that I have used boots OK.

Every sdcard adapter, not so.

The RPi 3B/3B+/3A+ will boot from external SSD drives, if set to boot from USB, & it uses an appropriate chip in the drive housing.

The RPi 4/400 will even boot from an external HDD, not just SSD drives, if it uses an appropriate chip in the drive housing or adapter cable.

After a bit of detective work I've found that the Netac ZX drive is PCIe based. The driver chip on the SSD is an SM2263XT.

I have also noticed that all of the articles about booting a Pi4/400 from an SSD, that I've looked at so far, tend to use SATA based devices. Lucy's article https://magpi.raspberrypi.org/articles/ ... -ssd-drive uses SATA, The Argon ONE M.2 case uses a SATA drive.

I know this is just anecdotal but I am now thinking that PCIe based drives aren't fully compatable yet

I now have a working combination.

I am using a WD Green 240Gb M.2 (not the quickest drive but a. cheap £25.99 direct from WD (free p&p) delivered in 2 days and b. runs very cool).

The enclosure is a UGREEN M.2 SSD SATA Enclosure USB 3.1 to NGFF (not a cheap enclosure but it was better to be safe than sorry)

I've been booting with WD My Pasport 1TD powered from Pi400's USB3 with no problems. I do use powered hub on second USB3 for other drives, K400r keyboard and sometimes a SDRplay RSPdx software defined radio.
