"Samsung develops high-performance PCIe 5.0 SSD

"Samsung has developed a high-performance PCIe 5.0 SSD for enterprise servers. "Samsung's PCIe 5.0 SSD delivers almost twice the data transfer rate and 30 % more power efficiency than previous generation SSDs.

Samsung Electronics, a global leader in advanced memory technology, announced on 23 December the launch of the PM1743 enterprise SSD, which features a PCIe (Peripheral Component Interconnect Express) 5.0 interface with Samsung's advanced sixth-generation V-NAND memory.

"For more than a decade, Samsung has been delivering SATA, SAS and PCIe-based SSDs that have been recognized for their outstanding performance and reliability by major enterprise server customers including enterprises, governments and financial institutions," said Yong Ho Song, executive vice president and head of the Memory Controller Development Group at Samsung Electronics. "The launch of our PCIe 5.0 SSDs, along with our PCIe 6.0-based products currently in development, will further strengthen our technology leadership in the enterprise server market."

"Intel has partnered with Samsung to test Samsung's latest PCIe NVMe SSD, the PM1743. During this initial evaluation period, we worked together to resolve the challenging technical issues encountered with PCIe 5.0. The performance potential of the Gen5 generation is truly impressive. We strongly believe that PCIe Gen5 systems with high-speed NVMe SSDs will be able to replace applications such as AI/ML and high-performance databases in the near future," said Jim Pappas, Director of Technology Initiatives at Intel Corporation. "As we look to the future, we are confident that Intel and Samsung's continued commitment to industry leadership will deliver these and other benefits to our joint customers."

PCIe 5.0 delivers 32 gigatransfers per second (GT/s) of bandwidth, double that of PCIe 4.0. Using a proprietary controller designed to support the latest PCIe standard, the PM1743 will deliver exceptional read and write speeds to meet the rapidly increasing performance demands of data centres.

"The Samsung PM1743 will feature sequential read speeds of up to 13,000 megabytes per second (MB/s) and 2500,000 input and output operations per second (IOPS) random read speeds, which are 1.9 and 1.7 times faster than previous PCIe 4.0-based products. In addition, write speeds have been significantly increased, with sequential write speeds of 6,600 MB/s and random write speeds of 250,000 IOPS, also 1.7x and 1.9x higher respectively. These excellent data transfer speeds will allow enterprise server manufacturers deploying the PM1743 to enjoy much higher performance.

In addition, the new SSD is capable of delivering improved energy efficiency of up to 608 MB/s per watt, an increase of around 30 % compared to the previous generation. This is expected to significantly reduce the operating costs of servers and data centres, as well as help reduce carbon emissions.

The PM1743 will be offered in a range of capacities from 1.92 terabytes (TB) to 15.36 TB in the conventional 2.5-inch form factor and 3-inch EDSFF (E3.S), an increasingly popular form factor specifically designed for next-generation enterprise servers and datacentres. Customers deploying 7.5mm EDSFF SSDs will be able to double the storage density of their systems compared to 15mm 2.5-inch drives. Combined with excellent signal integrity and thermal efficiency, EDSFF is ideal for most PCIe 5.0 enterprise solutions.

In addition, the PM1743 is expected to be the industry's first PCIe 5.0 SSD with dual-port support, ensuring server stability and high availability in the event of single-port connectivity failures.

Data security has become increasingly important in the enterprise server market recently. To ensure that these needs are met, the Samsung PM1743 will incorporate advanced security features that have traditionally only been available at the server level. With the addition of a security processor and Root of Trust (RoT), the SSD will be protected against security threats and data tampering to ensure data confidentiality and integrity, as well as enabling the secure boot of server systems through attestation.

Samsung is currently supplying PM1743 samples to global chipset and server manufacturers for co-development. The company plans to begin mass production of the PM1743 in the first quarter of 2022 as it continues to foster a highly reliable ecosystem for the new PCIe 5.0 standard.

The PM1743 has been named a CES 2022 Innovation Awards Honoree in the Hardware and Components category.
