Help with SD card choice for OSMC on RPI 3B+

I am working on setting up 2 Pi 3B+ osmc clients and a media server using a Pi 4. From the list of sd cards that I have made below what combination do you think would provide the best result? I am thinking that one of the 64gb cards would be good for the “server” as my goal is to store some media on the card, but I am not sure otherwise. I also can’t find clear info, beyond class 10 or better. Thanks in advance!

Thanks What are the specs of the card?

I think you will find that any decent quality SD card should work just fine but I would suggest to not use them for media storage. For that I would recommend a self powered spinning rust style drive, preferably in the larger form factor (the ones that contain 3.5" drives).


Regarding SD card performance on a Raspberry Pi there can be found tons of links, this I find impressive.

Thanks! Since the server is designed to be portable(And likely wont require a lot of media storage) I will probably end up using a USB 3.0 drive for the share, but thanks for the tip about not storing media on the card.

Thanks for finding that! That helps a lot.

Portable server with two clients? The storing media on a SD would be fine if you have a fairly static data set (something like a music library that doesn’t change much) and your card is much larger than what you plan on storing on it. In a nutshell you want to minimize the amount of writes and have plenty of free space to maximize the longevity of the SD. As such shuffling a bunch of video or other files files is best done on a secondary drive. If portablily is more important than lifespan then storing on a thumb drive may be an improvement, but you might want to consider a USB connected SSD as well.

Please note there is an issue with microSD cards greater than 32GB and Raspberry Pi.

On the other hand the best card for a Raspberry Pi after searching the Webb and looking at many tests is

Samsung Evo Plus MicroSDHC Class 10 32 GB

I have a couple of Pi:s and the microSD card that crashed was the one running OSMC. The other Pi:s was just running simple services like dns and such.

I attach a USB-stick to my Pi:s for logs and other stuff to lower the read/writes on the microSD card.

I think that moving the home directory to an USB-drive would keep the load of the microSD card.

What issue would that be? Perhaps your thinking about the issue with RPi’s not being able to boot from an exFAT partition? OSMC makes a small FAT boot partition and the remainder of the drive gets formatted into ext so this should not be an issue.

Thanks for pointing that out. That’s new to me. I just meant in general … but OSMC solves that issue out of the box. Great to know. More kudos to OSMC-team.
