I know IDE is fairly easy to interface to but what about SATA. I see a lot of projects with IDE examples but nothing approaching=20 SATA. As more hard drives move to that interface I would like to be able=20 to use them for data storage on projects. I looked around for SATA=20 chipsets and other than the chipsets for things like motherboards , USB=20 seems to be the only way to approach the interfacing of pics to SATA. What are others thoughts on using pics or even something like ARM with=20 SATA ?
