4.6 Storage Ports
I-SATA 3.0 and S-SATA 3.0 Ports
The X12DPFR-AN6 has eight I-SATA 3.0 ports (I-SATA0~7) and two S-SATA (S-SATA0-1)
ports. These SATA ports are supported by the Intel C621A chipset and provide serial-link
signal connections.
NVM Express Ports
Three NVM Express ports are located at JNVME1/JNVME2/JNVME3 on the motherboard.
These NVM ports provide PCIe 4.0 connections and provide high-speed low-latency
connections directly from the CPU to NVMe Solid State Drives (SSDs). This greatly
increases SSD data throughput performance and significantly reduces PCIe latency by
simplifying driver/software requirements.
