Samsung Electronics has launched a high-performance SSD based on the industry's best PCIe 5.0, improving read and write speeds by approximately two times compared to PCIe 4.0 and pioneering the high-performance SSD market.

Samsung Electronics announced on the 23rd that it has developed the high-performance SSD 'PM1743' for enterprise servers compliant with the PCIe 5.0 standard.

PCIe 5.0 is a next-generation PCIe communication standard that supports 32 GT/s, which is twice the bandwidth of the existing PCIe 4.0. It is expected to be widely applied to data centers and enterprise servers where the amount of data to be processed is rapidly increasing, such as in the recent metaverse and artificial intelligence (AI).

Samsung Electronics has achieved industry-leading performance by equipping the PM1743 with the 6th generation V-NAND and its own PCIe 5.0 controller.

The PM1743 boasts a sequential read speed of 13,000 MB/s, approximately 1.9 times faster than previous PCIe 4.0-based products, and a random read speed of 2,500K IOPS, approximately 1.7 times faster. Write performance has also been significantly improved, with sequential and random write speeds increasing by approximately 1.7 and 1.9 times, respectively, to 6,600 MB/s and 250K IOPS.

PM1743 supports dual ports based on PCIe 5.0. Even if a device connected to one port fails, service can be provided using another port, ensuring stability and high availability of server operation.

The PM1743 also incorporates security technology. Its built-in independent security processor and Root of Trust (ROT) prevent external security attacks and information tampering, providing the same confidentiality and integrity found in traditional enterprise servers. It also supports security attestation with server systems.

Additionally, the PM1743 provides a sequential read performance of 608 MB/s per watt, which is approximately 30% higher in power efficiency than the previous model (PM1733), and can be expected to reduce server and data center operating costs as well as carbon emissions.

PM1743 won an innovation award at CES 2022, which will be held in Las Vegas, USA next year.

“Samsung Electronics has enhanced the competitiveness of its SSD products by differentiating core technologies in controller design to improve performance and power efficiency,” said Song Yong-ho, Vice President and Head of Controller Development Team at Samsung Electronics’ Memory Business Division. “Samsung Electronics will drive the growth of the PCIe 5.0 SSD ecosystem through cooperation with major server and CPU companies and lead the upcoming PCIe 6.0 era.”

Samsung Electronics plans to begin mass production of the PM1743 in the first quarter of next year, and it will be released in two form factors: the 2.5-inch standard for existing general-purpose drives and the E3.S standard for next-generation enterprises and data centers, with capacities ranging from 1.92TB to a maximum of 15.36TB.
