Will a Haswell 13" retina MBP SSD work in a 2012 13" rMBP?

[marvel2]

Hi all,

I'm selling my 13" 2012 rMBP and getting a Haswell 13" rMBP. However, the 2012 rMBP has a 256gb SSD and the Haswell will have a 128gb SSD.

Can I swap the two SSD's between both machines?

Thanks!

No, first generation's use SATA3 and the second generations use PCIe.
