How fast is MBP's SD card slot?

[yauwing]

Toshiba just announced a micro-SD with speed as fast as 250 MB/s


Not sure if my 1st generation retina display MBP can take advantage of it.

All retina MBPs are equipped with SDXC card reader which connected to USB 3 bus, so yes, your rMBP will be able to take advantage of the card.

I thought about a 64gb sdxc card without a windows 7 on it to have for when needed. Won't protrude out like a USB stick. Do the new rMBP boot from SD?

Yeah, you can boot from SD I believe but it can't just be a DMG file. See this link: https://discussions.apple.com/message/20798607#20798607
