USB isn't bad besides the wireless interference with 3.0+

The only thing going for SD cards these days is the form factor. They're actually quite slow, considering they're flash based.

I think we're at 200GB for MicroSD. SanDisk has one, don't know if there's anything larger.

I believe that was the point.
SSDs are a lot faster than SD cards, despite using the same basic principle.

"Considering they're flash based" implies flash is slow.

SDcards typically have a powerful MCU and an undocumented and insecure firmware upload interface. You can hack them just like hard drives:

they aren’t as widely used because most computers have usb ports but not many computers have sd card slots.

also you cant attach them to your keys like you can with a usb, i know you can get little plastic holders and shit but its not the same.

I would much perfer sd cards as the norm but it wont happen.

You'd be fucking amazed where you can find an 8051, or a Cortex-M0, or even an M68000. I bet the keyboard you're typing on now has one. Or your screen. Maybe your mouse.

Today's microcontroller is the microcomputer of two decades ago, with some tweaks - but it's still a computer. And it's a cornucopia of undiscovered, unexplored vulns.

Thank the NSA TAO catalogue for reminding us of that, I suppose.

>undetectable
It's not inherently undetectable or unpreventable, you just have to treat USB devices untrusted in the OS level. It can be accomplished by using strict udev rules for usb and hardening the usb drivers. It would cause quite an inconvenience for handling USB devices though since it would essentially remove "plug and play" which is the main cause of the vulnerability.

By lightweight, you'll probably need something ancient. Some form of DOS or something since even the lightest modern system isn't gonna run well on 100mhz.

Now you need to port it to run on that cpu. Have fun.

Anyway how would you input/output? You can't plug in a keyboard or a monitor to an sd card. If you could it would probably be possible but nah.

Depends on what ARM processor they use, pretty sure uClinux will run on a Gameboy Advance which uses an ARM7 processor from 1998 running at about 17 mhz.

>Anyway how would you input/output? You can't plug in a keyboard or a monitor to an sd card.
If it can do one input line and one output line you could could use a serial terminal from another device with an appropriate adapter.
