i don't think you can, cuz it uses different m.2 key compared to normal nvme like in pc
Yeah, the R5C uses an E Key. Most SSD's are M Key. Tough to find an E Key 2230 form factor SSD. If you can find one, be aware E Key will be slower than M Key since E Key has fewer PCIe lanes - probably won't matter for casual storage though. There are cards to convert from A/E to M, but that arrangement is not going to fit inside a NanoPi R5C.

Does either work, SATA or nvme?
Would this work?

It's SATA and the typo in the description is not promising.
I think it is only nvme. 
I can't find anything cheap.
The only use I can think of is to store logs (nlbw, system-configs, collectd, ...). 
I currently use a small USB drive.
I'm going to plug in a USB wifi dongle so it'd be nice to free up the other USB.
Is there a M2 to USB adapter?
It's a tiny USB drive, it might fit.
issue is it's possibly E key m.2 which is only for wi-fi modules

there exists one card, see https://www.cervoz.com/products/industrial-m.2-2230-embedded-module-T425/detail
but be aware, zou will probablz need a custom kernel, since bz default there mazbe no PCIe support for SSD compiled in.
prices (for germany) are: 43€ for 64GB, 53€ for 128GB and 114€ for 512GB. quire expensive.
The NanoPi R5C seems faster than the Raspberry Pi 4 I had.
I've been using R5C for a while. Messed up with my wi-fi setting and want to restore the default /etc/config/wireless. Where do I find friendlywrt default conf files? OpenWrt locations /overlay/upper/etc/config/ and /rom/etc/config/ don't seem to store default confs.
Maybe in uci defaults ?

Could you delete /etc/config/wireless and then see what happens?

I’ve never done this before but you can try this:
rm -f /etc/config/wireless
wifi config
From this page of the documentation:

Hello here,
In case someone can help me regarding imagebuilder and R5C:
The OpenWrt Firmware Selector do not have unlimited resources, build the firmware without docker, install it extend the rootfs and manually install docker.
On the image builder you can use the option ROOTFS_PARTSIZE=
make image PROFILE=friendlyarm_nanopi-r5c ROOTFS_PARTSIZE="1040" PACKAGES="luci....."
Thanks, I know all of this. But I get was getting several errors about dependency in image builder.
Fixed now.
Nevertheless, thank you for trying to help me
In few days I should receive R5C. What is the current procedure to switch to snapshot and maintain it after?
I guess sysupgrade via stock Wrt will do, but will future upgrades cause any problems? I'd like my OS to be on eMMC and I hope lack of console/serial will not cause any problems.
Can anyone tell me how is the snapshot currently working on this model (NanoPi R5C). I think I’ll replace my MT2500 with this one

I'm running OpenWrt SNAPSHOT r27350-c4a9265160 from yesterday on my R5C gateway. I use squashfs images so I can keep settings when I sysupgrade. It is flashed to the eMMC.
Nothing too challenging: Adblock, CAKE, dns-https-proxy, and several vlan's for home network.
Everything I use is working fine, as it has on prior main snapshots. It has been quite stable in my experience.

Last week I flashed a new R5C. Mine came with FriendlyWRT which should work well but I prefer the original openWRT.
I went to the emmc flash tool in the same menu as upgrade. I flashed the factory squashfs image from firmware selector.
Did all this without sdcard installed. Be careful: internal emmc is mmcblk1 (not 0)

Thanks, I will mostly use it as a WireGuard server, all the other things I use are on my main OpenWrt router
Thanks for confirmation, just upgraded mine (via eMMC menu).
Did you manage to expand the filesystem, as default is only 88MB (/overlay)?
Will it stay after sysupgrade?
