Got my hands on a Dell Latitude ON module. Turns out it’s nothing more than a 2 GB flash module that fits in a mPCIe slot and is wired to the USB lanes. Shows up as /dev/sdb.
I do have a couple of old laptops that don’t have a secondary SATA drive slot, but do have open mPCIe slots with USB lanes (no mSATA lanes). The Latitude ON module would allow for a dual drive system, albeit a rather crappy one. What would you put on a secondary internal drive if it were limited to 2 GB and USB protocol?
Incredibly simple, free, and quick thing to add for user confidence. Doesn’t sit well with me they can’t be bothered, what else does that attitude apply to in the OS?
