emmc / sd or ssd?
#1
Hello,
   I have a question/remark concerning the "choice" between emmc / SD or ssd. Currently, the regular price for emmc of 64GB is rather in the same order of magnitude to a ssd of 120GB NVME. If I am not wrong, the SSD has a better performance than emmc, therefore, if it were possible to boot from PCIE, does it worth using emmc ? I read in the forum that many attempts has been done but end with a mix emmc for boot and ssd for root. @pine64 team : is there a really possibility to make the rockpro64 boot from PCIE ?    

Best regards

My favorite is boot from sd-card and root system on an pcie nvme ssd.

For boot from ssd we need an working u-boot. At the moment not possible.
Sorry for any mistakes. English is not my native language

1. RP64 v2.0 / PCIe NVMe as root / sd-card as boot / 2,5 Zoll HDD 1TB (USB3) using as Webserver .... (Kernel 4.4.167-1140-rockchip-ayufan-g6f266fb5d677)
2. RP64 v2.1 / PCIe SATA Marvell 88SE9230 Chipsatz / sd-card / 2 * 2,5 Zoll 2TB HDD (raid1) / using as NAS / Kernel 5.0.0-1101-ayufan-g41eeb7cd789e
3. RP64 v2.1 / testing.....testing....testing

I read your posts, and I think that this is the best solution for performance (thank you for having shared your experiences). That's what I am going to do !
What I can also try is a network boot (PXE) with a root on SSD. I almost succeeded to boot (it boots but with some problems after) with nfs but never tried with root on ssd.
Is it possible to boot with USB-C ? I have a case with PCIE to USB-C converter.
