SD vs Micro SD (with adapter)

Hey there!

I just got my TX2 board and I have the following doubt: Under same specifications of performance, will a Micro SD with SD Adapter be slower than a full size SD on TX2?

I doubt physical size would matter, but there seems to be a big difference from brand to brand of SD card. There also seems to be a lot of differences between specs of individual cards which isn’t always obvious without reading the fine print. I think to compare you’d need to get the same exact model in both form factors…not sure how practical that is. Certainly an adapter makes it harder to retain signal quality, and if the same card is operating at the limits of its abilities I could see the possibility that extra trace length from an adapter would interfere on the adapter form factor.
