I just got a brand new MacBook Pro Retina 13" model 2 weeks ago, love it! 9 hours of battery life, 8GB RAM, 512GB SSD, 802.11ac Wi‑Fi and Bluetooth 4.0 wireless, two Thunderbolt 2 ports, two USB 3 ports, an HDMI port, an SDXC card slot, and a headphone port. Thin, light, so fast. I'm looking for a low power blu-ray burner/reader for it. Ideally it would power off the USB 3 or Thunderbolt 2 port, I don't care, just don't want to lug a power brick with me. Any advice on good choices, from people who really have them I appreciate it. (yes, I can do a search and find them out there, I'm looking for feedback here) 1) do they work good powered solely off the laptop battery 2) can I burn a blu-ray from laptop solely, or is that rolling the dice for mis-burn? 3) etc thx in advance for feedback.
