Raspberry Pi 4 Model B SBCs with micro SD and eMMC is running in single data rate mode only. However, it is capable to support the double data rate (DDR) mode. Manjaro Linux developer Tobias Schramm brought everyone’s attention to that recently. He has also sent a mail to the kernel mailing list.
Tobias has sent out a patch in device tree file. This should theoretically double the transfer speeds to the eMMC/SD storage. So far no kernel developers or Raspberry Pi Foundation staff have commented on the proposed patches for the mainline Linux kernel.
