Hey folks I'm running out of space in my 13' rMBP, late 2013. As you may know, this MB runs a PCIe SSD, and, until today, i thought there were no options on the market for this upgrade. Today, searching on Plextor website i found this: http://www.plextoramericas.com/index.php/pcie-ssd/m2/m6e-m2-2280 This is a PCIe SSD Gen2 x2, and i was thinking if it will possible to upgrade my rMBP with one of this SSD. Is anybody using this SSD in their MB? Is it working?
