Late 2012 MBA SSD & 2013 MBA SSD Interchangeability

So I spilled an adult beverage on my late 2012 MacBook Air 11" I took it to Apple and they were able to backup my data on an external HDD.

Yesterday I purchased the 2013 MacBook Air 11" and I was wondering if there was a way that I could switch hard drives...just so I can erase my personal info on from it. I obviously don't want to make it a permanent switch.

I heard that the 2013 SSD is smaller compared to the 2012 version.

Any ideas..???

I have the data I need on an external HDD already...this SSD from the 2012 MBA is still functional so I'd like to get rid of it, but before I do I need to erase all my information from it.

Is there some sort of cable that I can use to connect as USB or something so I can format and run some integrity tests on it??
