I can't confirm it but your assumption makes sense.
It also means trouble for what is fast enough to write to it! RAW at 60p would be 540MB/s
Taking a look at the most expensive cards on B&H:
ARRI 512GB Extreme PRO CFast 2.0 Memory Card - 450MB/s
Angelbird 256GB AV Pro CF CFast 2.0 Memory Card - 400MB/s
Lexar 512GB Professional 3500x CFast 2.0 Memory Card - 445MB/s
ProGrade Digital 512GB CFast 2.0 Memory Card - 450MB/s
of course, sane people would just shoot compressed, but considering this thread is about specs...
Why didn't they bring over the internal SSD from the BMCC/BMPC4K? CFast is way more expensive, and SD cards aren't capable of these speeds. If they wanted to make this camera an affordable proposition, then an internal SSD would be miles better. The external solution isn't ideal for all recording situations.
