With a twist of a T8 screwdriver, the SSD assembly is easily removed from the device.

For those playing along at home, we have only removed one screw, and the SSD is out. (Side note: the screw wasn't even proprietary!)

On board we find some rather familiar friends:

Samsung S4LN053X01-8030 (ARM) Flash Controller

Samsung K9HFGY8S5C-XCK0 Flash Storage

Samsung K4P4G324EB 512 MB RAM

This combination of hardware makes the Mac Pro's SSD suspiciously similar to those we've seen in the latest refresh of MacBook Pro Retina and MacBook Air.

To the point that only the last few digits of the model numbers are any different. Hmmm...
