So this is my second arduino project and as usual Im buying stuff without much of an idea as to what im doing. I've been cruising the forums for a bit and it sounds like there isn't any simple way to interface the arduino boards (my AT Mega 2560) with large storage devices(IDE/SATA). I'm looking to build what is essentially a security system and I'd like to have at least 2, preferably 3, cameras in the 1-5 Megapixel range recording 30fps video to... something. The SD card breakout for the arduino sounds nice but at a max of 250G thats less than 24h of recording in a high compression non-HD format.
^^ That's all kind of back-story. My main question is:
-what is my best option for absolute max storage for my 2560?
-Can I attach a bunch of those SD breakouts to one 2560? It seems like I can since they just hook into the digital pins, but is it a huge hassle to handle 3 or 4 SD Breakouts?
Last note: Im planning on having the cameras overwrite old recordings, so Im not trying to save everything in perpetuity, but I would like to get more than 24h stored video.
