Hello. I don't know if I’ll have problems booting from a SDXC card larger than 64GB. Maybe there is a card size limit with the Dreambox One. I think this Sandisk Extreme is supported:
Although my idea was to buy this one, much, much more expensive:
Will there really be an appreciable performance difference? A priori, it does seem so. 200 Mb/s vs 300 Mb/s, UHS-I Class vs UHS-II Class, V30 vs V90. But I don't know if the last card is supported by Dreambox One. The same thing happens with the next two.
This time it’s something in between the two previous card, Lexar. That is, 250 Mb/s and V60 but UHS-II like the second Sandisk:
Another option, Kingston, apparently identical to the more expensive Sandisk, but at half the price, is this one:
These are the options I am considering at the moment, without clearly deciding on one of them yet.
