Moving from SD Card to SSD (open discussion)

@Lolonois said in Moving from SD Card to SSD (open discussion):

I left the boot (/boot) partition (less than 200MB) on the SD card and the root filesystem (/) on the SSD, as described there [7]. This way I don't had to change the boot order via raspi-config

What is the benefit of this? Why not replace the sdcard entirely and only use the ssd?

Lolonis probably just didn’t want to go through the process of updating the boot order. By default it boots from the SD but you can use the raspberry pi imager to change it to boot from usb first. Look through the first 8 steps here.

@Retro-Arcade-Fan I would have had to have the RPI firmware updated, which breaks the screen rotation on a very few emulators I am using (mainly those which do not use SDL2 or libretro). I need screen rotation as my display is mounted 180 degrees rotated and I can not mount otherwise due to space limitations. And last but not least: The 2GB SDcard was collecting dust anyways in my drawer. :) TL;DR: On a new build I would put everything on the SSD.

ok, so to confirm, I'd be better off with:

Then all I need to do is follow the steps at https://www.tomshardware.com/how-to/boot-raspberry-pi-4-usb to change the boot order and I should be good to go?

Am I missing anything?

Depends on what you want: As far as I understood it, it changes the boot order from SD over USB to USB over SD... so, without that steps applied and as long as no SD Card is inserted into the Pi, it should boot from the first USB device it finds with a boot partition (see Pi4 Boot Flow). AFAIK (and in my experience) USB Boot was factory enabled for all Pi4s from the first revision onward.

The Pi PSU, will handle this case with the fan and extra board ?

@windg As neither my 4GB Pi4 [1], nor my Arcade-build of a 2GB Pi4 in an Argon Neo casing [2] are having any power problems, that shouldn't be problematic... unless that M2 Sata to USB adapter + the SSD is drawing more power then that. [Edit: I am running both systems with the official Pi4 PSU and no OC applied (and both machines are to old, no gain from arm_boost=1)]

1: Argon One casing (1st gen) and an external HDD (old Laptop 2.5" 300GB SATA + external USB 3.0 casing) with the Raspberry Pi OS running from the HDD.
2: with 2 2.5" SATA 128KB SSDs mounted in external USB 3.0 casings (mounted via fstab: one holds the home folder, the other one is for screenshots, videos and some other stuff) and running RetroPie from a 32GB SDCard [The Neo case is passive, no optional fan mounted].

Note: It looks to me that in 1.) the SATA extension is already included, so no need to buy also 2.)

Note: M.2 SSD only denotes the physical format (either "long" 2280, or "short" 2242). The second important factor is the bus protocol: This can be SATA, PCIe or NVMe. Thus: When picking a SATA (Argon case) the M.2 SSD must run SATA protocol. The SSD you suggested in 3.) won't work in the Argon SATA case. So either go with SATA M.2 SSD (Western Digital and Crucial are also fair picks) and accompanied Argon SATA case or with a NVMe M.2 SSD and an Argon NVMe case.

Then all I need to do is follow the steps at https://www.tomshardware.com/how-to/boot-raspberry-pi-4-usb to change the boot order and I should be good to go?

I never used the procedure there but with retropie it would be in theory:

Get Retropie-Image from retropie.co.uk
Put on SD-card (as outlined in the Toms Hardware guide)
Install Pixel Desktop: https://retropie.org.uk/docs/FAQ/#where-did-the-desktop-go
Launch in to the GUI, then there should be this SD Card Copier.
That should be it.

SATA M.2 SSD

What's difficult, especially on Amazon is they throw in a lot of terms that don't always pertain to the actual product. I've seen SSD that say SATA, PCIe, M.2, and NVMe all on the same card.

Would this one work with the Argon sata case?

@Retro-Arcade-Fan I have seen the product number ‎WDS500G3B0B on the amazon page. This denotes the SATA variant.
