Wanting to deal with data at that rate is something I WANT to do now.
Whether a given processor can handle it is another matter:-).

With relatively minimal hardware, eg video, streaming hardware ADC capture
from eg a scope front end, RAW delta sigmas DAC data (maybe lightly hardware
framed), ... ? No? However, such applications MAY be costly enough overall
to justify a somewhata up mraket processor. But, this is not necessarily the
case. eg as memory card specs increase a card reader may like to dump output
from a 600X CF card.  Memory suggests 300X is 30 Mbps. 600X twice that.

45 MB/sec.

600X CF now

UDMA 6 guaranteed 90 MB/Sec sustained minimum write speed.
$US200 8 GB. Almost worth it :-).
$US300 16 GB.
My obsolescent SONY A700 can generate around 100 MB/second (RAW + jpg at 5
fps)

A more capable processor is allowable if a bottom end one won't handle it
:-).
