Hi guys, I am hoping to upgrade the blade SSD in iMac 5K. The SSD used in iMac 5K only has x2 bandwidth, so it is not so fast as the SSD used in nMP and latest rMBP 15". Does anyone know if it is possible? If I get a x4 SSD (blade SSD part for nMP, for example), will it work on my iMac 5K with full speed? Thank you!
