I repost this here because i was told on stackoverflow that my question was off-topic.
I would like to connect a lot of SATA hdd on my raspberry PI. I've read about how are sata pins made and I can create a power source myself. But i'd like to connect the hard disk through raspberry's GPIO, and to access it. But I have no idea of how I can control my disk directly with SATA signals. Is there any source code I could adapt to mount my wierdly-connected disk on the raspberry pi. I don't need a fast connection, the purpose is to save data. I can do the electronics requiered, and I have already a SATA cable which I can connect to the raspberry. My question is just about the software-side of the problem. At least, is it possible (can GPIO reach frequencies requiered by SATA protocol, for example).
Thanks for reading my bad english
