> Is there any high quality SATA cable in the market? especially with teflon insulated, silver or silver plated.

Even if there are such SATA cables, you would be wasting money and effort using them. The picture quality of the digital video cannot be improved (nor be subject to deterioration) by the cables carrying packetized digital data.

You really should educate yourself on the differences between analog and digital video, and storage and transmission methods. The disadvantage of digital video and audio is that the continuous waveform has to be sampled and quantized. For digital video (and some audio formats) that data is then encoded and compressed and some information/data is thrown away! The big advantage (once the video is digitized) is that this data stream can be stored/transmitted and then retrieved/received with high integrity. No noise can be added to the digitized data. If the signal is corrupted, then it will be detectable (and maybe even correctable). It's when you want to convert that digital video or audio signal to analog is when you need to be concerned about noise, impedance et cetera again.

BTW I have Nordost teflon-jacketed, silver-plated interconnects in my audio rigs, but that's for low-level analog audio. Computer and other digital cables only need to be just PVC-jacketed plain copper.
