Dunno. It's probably an artifact of Rigol making sure that the device can not be crashed via fast SCPI commands or so, the DS1xx2 series apparently could be crashed that way. Didn't happen once during my experiments with the DS2072. 14 MSamples are not useful/sensible for live display at something like max. 2000 horizontal screen pixels anyway, so that should not be a concern. Well, until one wants to do digital phosphor with horizontal oversampling data. The usecase I see would be to capture something like I2C at high sample rate and relatively slow timebase, maybe digitize it, and then analyze it. Time to get at the data should not be that important then. Anyway, I guess the scope is a USB Full Speed device only (have not checked that though), so technically it might not be able to transfer much more than about 1MB/s, which at 10s-14s for 14MSa wouldn't really help.
