M.2 Storage format

[mestrade]

Hello,

I’ve tried to use a Samsung SSD 980 (nvme M2) without success. The M.2 connector doesn’t fit.
Is there a specific format to use for the M.2 storage port ?

You’ll need to use a SATA M.2 B-Key like the Samsung 860 EVO. The Samsung 980 NVME is likely a M-Key. I don’t think NVME devices are supported.

I just inserted a Samsung 860 EVO SATA SSD into the M.2 slot and it seems to be working fine.

Performance is 73.7 MB/s for the SSD vs. 20.1 MB/s for the internal MMC.

SSD:
dd if=/dev/zero of=./zeros conv=fdatasync bs=384k count=1k
1024+0 records in
1024+0 records out
402653184 bytes (403 MB, 384 MiB) copied, 5.46706 s, 73.7 MB/s

MMC:
dd if=/dev/zero of=./zeros conv=fdatasync bs=384k count=1k
1024+0 records in
1024+0 records out
402653184 bytes (403 MB, 384 MiB) copied, 20.0723 s, 20.1 MB/s

I’m supposed to receive mine today. I also have a usb enclosure for this model so I will try to install my rootfs on this disk and then avoid booting on USB which is buggy at the moment.
