Q: Will this thing support if I connect external HDD's or Flash drives to watch movies or transfer photos?

The CCK is mainly use to transfer pictures and video from SD Card and camera.

You cannot use it like the way you connect an external drive to a laptop.

You can use the GoFlex Satellite wireless storage to stream movies to your iPad

Theoretically you can put movies and videos onto an SD card, satisfy the naming requirements - all files in a DCIM folder and with a name of exactly 8 characters. Then you can use the photo app to import that video file onto your iPad, watch it and delete it.

Does require that you have the room to import....so it's not perfect but it does work.

but if you want to watch a lot of movies and video files, the seagate is probably the best way to go since you can keep tons more than what fits on a 4-32 gig card (which start to get pricey after a bit)
