My main requirement of the NAS is as follow: 1. Being able to stream HD videos/audios to my mac, iPad either from inside or outside of my home network. 2. Mac and iPhone user friendly 3. Time machine 4. SSL VPN 5. Download torrent occasionally I think both can achieve point 2-5. However, my main concern is about the first point. I know that the Synology can transcode the media file before streaming to the devices, thus the devices can play the video no matter what format it is in. Can QNAP do that? Or what QNAP does is transfer the files to the devices and the devices does its own transcoding? Thanks in advance!
