What is the Max size for SD card.
Mine is here tomorrow.
I got junkie XL’s off of reverb.
I do feel kind of bad not getting a new one to support this awesome company
But a deal is a deal.
It comes within a 32gb San disk extreme sd card (iirc).
It’s important it’s a very fast high quality sd card otherwise you will have issues.
The sdcard image provided is 32 gb, so by default that is all you will see available even if you have a bigger sdcard.
If you have Linux experience then you could start expanding or or creating file systems to make use of bigger cards…you could even use a usb drive.
However you’ll have to work out a way to access it from synthor.
For now I’d stick with the 32gb it’ll be enough to get you started 
This topic might also be interesting to you
Thank you
32 gb will be fine for now
Finally getting it today can’t wait
Happy patching … enjoy the journey.
Could anyone who’s been able to use a 32GB SD card (other than the SanDisk’s one that originally comes with the unit) without any issues tell me which SD card you’re using?
A sudden NAND flash’s death is something no one can escape — it’s inevitable for everyone sooner or later, and nobody knows when it’ll happen
— so I’m thinking it’s about time to buy a backup. I’d like to know what options exist besides SanDisk.
looking at what I have around, labelled as SSP, (Ive many sdcards for it) , I think I used a 64gb sdcard at some point, a similar sandisk one (I trust sandisk, as never had issues)
so, heres the thing… you should be fine with any similar (or better) spec card, and could likely use very large cards- however, as I mentioned in post above, you’d need to repartition the sdcard image to make use of it.
also bare in mind,
- larger capacity sdcards have larger block sizes, so if you want to do things like streaming, can perform worst than smaller cards.
note: if you are loading into memory, then this is a non-issue, its just streaming. - sdcard performance is also limited by the ssp hardware controller.
ie. getting a super fast / expensive card may not yield any better results.
overall, technically, you can probably use whatever you want, SSP is using a reasonably modern linux kernel, so support should not be an issue.
but Ive never really seen any reason to not use what came with it… esp. as they are now so much cheaper than they used to be.
personally, Id prefer a bunch of 32gb cards, and swap them around, than using a bigger / more expensive one. its cheap, and gives you backups 
all that said, Ive not exhaustively tested, as Ive been happy with the sandisk cards 
Thanks for the detailed comment.
Yeah, SanDisk SD cards are great!
(The inside is basically the sweat and tears of Japanese craftsmanship!)
Since I don’t want to repartition anything, I’ll look for a 32GB card with similar specs.
i made a backup of my whole card this weekend, just to be able to flash the whole card again if something goes wrong
noticed the boot volume is around 20GB
can we enlarge this with the right software?
say, get a 64GB SD card, flash that card with the earlier image and then enlarge \boot from 20 to 40GB ?
yes, you can change partition sizes with linux, just as you can with any other OS.
there are two important partitions on the sdcard
part 6 = BOOT , fat , ~ 20gb (what you see when you mount on your computer)
part 7 = rootfs , ext4, ~10gb
the minor complication is the ext4 partition follows the fat partition, so you need to ‘resize’ the BOOT partition by moving the rootfs, it cant just be ‘extended’
so your tool would need to know how to do this, and so it might need to know about ext4 partitions (not that these are unusual, linux has used for years)
tl;dr;
I’ve done this in the past in linux using resize2fs (iirc), but it may be fine with other OSs disks management tools (e.g for windows/mac), its just I personally, like to do on the ‘native OS’.
another option would be to create a new fat partition and to then get linux to mount that.
( I don’t think, ssp’s linux config will automount other partition, though it might… I havent tried
)
this could be kind of nice, as it could fit into support for external media like usb drives.
overall, its never been an issue for me, as I don’t really use samples… so 20gb has been more than I need…
the reason, I was resizing partitions previously was mainly to extend rootfs.
I was installing more linux applications and dev tools/ libraries, but thats not really an issue since it moved to buildroot, much less is installed by default
