Which USB M2 Adapter works best with Raspbery PI? Especially with booting from the SSD?
I read different statements in the forum which chipset would work at the best with the Raspberry: JMICRON JMS578 or ASM1153E?
I'm afraid it's not that simple. I have multiple adapters with both of those chipsets, and examples that work and don't work. It's a combination of the chipset, firmware, and the SSD in use. For instance, I have one adapter that works with 4 other brands of SSD but doesn't like my Samsung SSDs, while another adapter with the same chipset works fine with Samsung.
There are even differences in the bootloader between the 3B and 3B+ models that affect the outcome (might work on one but not the other).
And finally, some cheap USB enclosures and adapter cables will change over time. You might buy one this week that works great, and purchase another one a few months from now that no longer works as desired. Which means that recommendations from others with the same adapter are helpful, but not a 100% guarantee.
So in the end it comes down to trial and error.
Sorry, I know that's not the answer you were looking for, but I have done a lot of testing with different adapters and a wide variety of drives, and there really isn't a simple answer. If you do get an adapter that doesn't work for you, using a bootcode.bin SD card will likely resolve your issues on the Pi3 models (but not the Pi4, since it doesn't use bootcode.bin). If you absolutely must have USB boot with no SD card, then understand that you might have to purchase and test multiple adapters.
