iMac Late 2015 - Upgrade SSD or use Apple Stock SSD
When buying the 1TB SSD with the iMac directly from Apple: Is it a PCI-Express SSD then?
Is the main HDD-Slot empty in this case (hence could I add another HDD later on?)
Doing the upgrade via Apple is like 400$ more expensive than upgrading yourself. Is the PCI Express SSD worth it? (If this is what apple uses)
Is this a good question?
