I want to buy Raspberry Pi 5. I am a complete beginner. I don't want to use SDcard, but I want to boot with an external SSD without using HAT.
For example I want to use [Crucial ® X6 Portable SSD](https://www.crucial.com/products/ssd/x6-portable-ssd) which has speeds upto 800 MBps. Since Raspberry Pi 5 can support USB 3.0 port at full speed (i.e. it provides 5000 Mbps = 625 MBps). So, can I install Raspberry Pi OS on the external SSD (not on HAT) and boot the Raspberry Pi 5?
Yes.
So if I do as above can I run Raspberry Pi 5 without sdcard and without NVME SSD HAT?
Also yes.
But there are two major caveats:
- The combined total current draw of all bus powered USB devices must not exceed 1.6A/8W and that assumes the official PSU.
- If your chosen combinarion of Pi and PSU cannot negotiate (via USB PD) a 5v, 5A supply:
- The Pi 5 will pause during boot and ask you to confirm boot by pressing the power button
- Total available USB current will restricted to 600mA
Code:
[all]usb_max_current_enable=1
