That's not what the datasheet[1] says:
When outputting DPI, PIO can sustain 360 Mb/s during the active scanline period when running from a 48 MHz
system clock. In this example, one state machine is handling frame/scanline timing and generating the pixel clock, while
another is handling the pixel data, and unpacking run-length-encoded scanlines.

Still not SATA speeds though.
