SATA Ports
The H12DSU-iN has eighteen SATA 3.0 ports (SATA0-17) that are supported by the chipset.
NVMe Connections
Four NVM Express (NVMe) ports are located on the motherboard (two for each processor).
These ports provide high-speed, low-latency PCIexp. 3.0 x4 connections directly from the CPU
to NVMe Solid State (SSD) drives. This greatly increases SSD data-throughput performance
from direct PCIe interface from the CPU to the NVMe SSD drives.
