Chosen Solution

Hello, when you buy an iMac Intel 27" Retina 5K Display 2019 and select 1Tb as the storage option, is it a NVMe 1Tb blade or a slower 1Tb SATA drive that they put in? Thanks JF

It depends which you selected!

The top one is a Fusion drive which is a 1 TB SATA drive with a 24 GB PCIe/NVMe blade SSD The bottom is a 1 TB PCIe/NVMe blade SSD alone.
