Seagate Demonstrates HDD with PCIe NVMe Interface

From Tom's Hardware: Seagate has demonstrated the industry's first hard disk drive connected to a host using a PCIe interface at the Open Compute Project Summit. Like solid-state drives, the experimental hard drive uses the NVMe protocol to operate alongside SSDs seamlessly. Usage of a single protocol for different types of storage devices will greatly simplify datacenters.

The experimental SSD is based on Seagate's proprietary controller that supports all three major protocols, including SAS, SATA, and NVMe over a 'native NVMe port,' and does not require any bridges. The HDD was demonstrated in a proof-of-concept 2U JBOD enclosure that used a relatively simple PCIe switch connecting to 12 3.5-inch drives using a PCIe interface.
