Ответ на "Are these the right SSD PCIe blades for iMac Late 2013?"i just found a PCIe SSD that works with the 21.5" 2.9GHz i5(the model that has the PCIe slot). i am getting about 650mb write and 710mb read; it is awesome. i was already getting great speed with the samsung SSD i have in the main SATA3 port but the PCIe is much faster. i am working now on identifying which SSD models are compatibles.
