I'm trying to make <a
href="https://www.beagleboard.org/boards/beaglebone-black">BeagleBone
Black</a> into a programmable keyboard (and mouse, hopefully). It
has one "USB device" port (mini-USB) and one more common "USB host"
port (USB-A). It boots off microSD or eMMC. One frustration is
slow speed of my SD cards. I have lots of them, 8-16GB and 5MB/s.
Too slow to flash images, and too slow to run on it.<br>
<br>
So, I've been shopping around for a <b>fast</b> microSD card. What
I don't understand is,<br>
- some U1 cards are faster than U3 cards. This means, I can't
just search for "U3" cards.<br>
<br>
- Do you know why U3 cards are slower than U1 cards?<br>
- Any brand recommendation?<br>
- Canada Computer has lots of "Teamgroup". Are they good? They
are new (to me).<br>
- Of course, can't go wrong with Samsung. But, not at $20
range.<br>
- no Kingston. All the dead cards were from Kingston.
