SSD for PBP

Hmm, if the eMMC modules use noticably less energy, perhaps we need to re-think the NVMe adapater. Go for a PCIe controller chip that lets us add another eMMC slot. This adapter would be smaller, and almost certainly use less power than the average NVMEe drive in M.2 form factor. Here is a one companies datasheet;

My preference would be a chip that did 2 x eMMC or UFS, (the newer standard which replaces eMMC). In the end, the fact that the NVMe adpater board is both optional, and reasonably easy to install makes having 2 types of storage cards possible. The end user chooses which they want.

In my case, I want a mirror drive to my OS. So I would be using both builtin and PCIe devices at the same time. (The OS partition would be limited to perhaps 30GB of both devices.)

Just wondering out Loud :
   IF it would be possible to add a second eMMC through the PCIe board connection,  do you think it would be possible to utilize as a raid configuration ? ?
