The FS4 is called a "direct to edit" device. For that use it
appears to be essentially instantaneous (because the processing
takes time too).
All hard drives will support that rate because they need that
burst speed.
In the future we may see devices for DV50 - so those disks will
need to support some 60mbps burst speeds, I would guess.
