How do I interface two SD cards in the same project?

plus an LED would only be 100 milliamps.

In spi mode it is less:

Power consumption to write to SD card?

I'm trying to determine power consumption of my project. It's a fairly straightforward circuit to download data over a serial interface, process it, and save it to an SD card. I'm using a Teensy 2.0 with the pjrc.com microSD adapter. Unfortunately, it's going to be a few weeks until I can test it in action. On the bench, I can power everything up and initialize the SD card, and measure the power consumption while I do that (~55 mA at 5v). Will actually writing to the SD card make a significant d…

Some very interesting (and damming) evidence for this voltage regulator if I want to use a Kingston card:

And from SanDisk:

What does everyone think? Should I risk using the NCP561SN33T1G?
