Recommendations for SD cards

I might be getting (hopefully) a Rpi 4 within shortly. I wondered if there is a “bare minimum” recommendation on the rw speed of the SD cards. I imagine the faster the better applies here but is there any bottom limit?

so far my best xp on Pi4 + Pinebook Pro if use sd card is SanDisk Extreme Pro. Have 5 @ 128GB . never let me down

I sure @Pudge be prob give best answer on this

I have a SanDisk extreme? Gold and red. It doesn’t matter anyway though, you should be able to USB boot.

I haven’t touched my pi in a while. I really should get on that.

Thanks for the replies guys!

Great, thanks! I’ll have a look at them.

Do you mean from an external drive, like a SSD?

as @fbodymechanic say … you can boot from ext ssd or nvme

Also from USB drive itself?
Then something like that is pretty reliable

That sounds great!
So I could just install the OS on the SSD using my laptop and then Plug&Play on Rpi?

Yes, exactly.

I have the whole set of them - 2 32gb (W10, and future W11 install .iso), a 64GB for timeshift on my one laptop - a 256GB for music on the go, and a 128GB for my pi.


Thanks a lot! I’ll have time to go through those threads during this weekend.
This will be my first experience with Rpi so I am a bit excited about it :blush:
