It’s identical in looks to the X98 Air II and Air 3G (No surprises here, we knew this already) The only difference to an Air II is the X98 Pro engraving on the back. The eMMC is a Samsung branded one on my unit. 140 reads and around 50 writes. Doesn’t seem like an eMMC 5.0 to me, but a 4.5.1 unit?
The rear of the X98 Pro does get quite hot, warmer than a Z3736F one I think. I will investigate this further with my temperature probe.
