    Looking at options to add more storage onto a new MBP retina, and was thinking about SD cards. They now come in fairly big sizes, but I'm not sure how fast they are compared to say a USB external 2.5inch drive.

    Anyone have any real world experience?

    Eh !!

    you are looking at comparing the write speeds of an SD card versus an external hard drive (connected via usb/firewire/thunderbolt)

    depends on which connection the external hard drive is connected with .... but I'd say most of them would be faster to use the external hard drive .....size is a different thing, the SD card is tiny while an external hard drive will be considerably bigger.

    and of course there is the reliability issue - corruption of data is highly possible with both SD/external hard drive ....more-so with the SD

    If you're looking for storage for the retina, get either a USB 3 drive or a thunderbolt, the speeds off most SD's are pathetic compared to the likes of USB 3 or TB. And if you were in the market for a fast SD, you'd get an even faster ext hdd with 10x the storage for the same price as it

    The latency is going to be at the read/write time, not transfer speed. Be it TB or USB3.

    SDXC transfer speeds are rated on the card.

    https://www.sdcard.org/consumers/speed/

    Class 10 will transfer approx 14.6MB a second (max possible speed of 20MB a second).

    Also be aware that SDXC slot is designed to leave a normal SD card hanging out.
