SSD for PBP

Would a pair of MMC modules possibly consume less power than one PCIe module  ?      As in the previous mention of Raid combination.

From the SanDisk eMMC data sheet, (it's on the PBP wiki), the 128GB module seems to run about 1 to 1.5watt maximum. And generally 1/2 to 1/3 that for simpler use. So it does look like a PCIe adapter board with eMMC adapter chip & memory module would use less power than many NVMe SSD drives. (Assuming the PCIe to eMMC adapter chip uses less than 1 watt.)

That's low enough that I would want a PCIe to dual eMMC adapter chip, if possible. The PCIe bus can certainly handle the throughput.
