So, a question... Does the iMac/Retina iMac have PCIe-based flash storage, or typical SATA III SSD? I've assumed it was PCIe (offering the same performance as the nMP and rMBP). However, while both the nMP and rMBP clearly say "PCIe-based flash storage" on their respective spec listings (and on the Apple Store while configuring both machines), both iMac models simply say "SSD Storage". I've seen teardowns of the iMac and it doesn't seem to include a typical 2.5 SSD drive, however the thought occurred to me that the flash storage could be still be SATA 3 based in the blade form factor. Anyone have any insight? If it is truly is PCIe-based, why would Apple's own tech specs not point this out?
