Vision Research’s Phantom v1610 shoots 1m fps, albeit at the rather low resolution of 128×16. At a more modern 1280×800, however, it still packs in 16,000 shots every second. A 10Gb ethernet link and other high-end connections will keep the data flowing; how many seconds of footage its 96GB of internal storage can hold is left as an exercise for the reader.
