The 2013 SSD upgrades will only work in the 2012 models and Early 2013 models, they will not work with the late 13's and the 2014. The Late 2013 and 2014 MacBook Pro's have a new SSD design, and no one has released a compatible one yet.

Alirod is correct. The part you linked is a mSATA (micro Serial ATA) SSD, but the late 2013 and mid 2014 models have transitioned to PCI-E (PCI express) SSD. The two are not compatible.
