For over a decade, Samsung has been delivering SATA, SAS and PCIe-based SSDs that have been recognized for outstanding performance and reliability by leading enterprise server customers including corporations, governments and financial institutions,” said Yong Ho Song, EVP and head, memory controller development team. “The introduction of our PCIe 5.0 SSD, along with PCIe 6.0-based product developments that are underway, will further solidify our technological leadership in the enterprise server market.

Intel has been working with Samsung to test Samsung’s newest PCIe NVMe SSD, the PM1743. Together, we have jointly resolved complicated technical issues encountered with PCIe 5.0 during this initial evaluation period. The performance potential of Gen5 is truly impressive. In the near future, we strongly believe that PCIe Gen5 systems with high-speed NVMe SSDs will have the ability to transform applications such as AI/ML and high-performance databases,” said Jim Pappas, director, technology initiatives, Intel Corp.Looking ahead, we are confident that Intel and Samsung’s continued commitment in industry ladership will provide these and other benefits to our mutual customers.

PCIe 5.0 offers a bandwidth of 32GT/s (gigatransfers per second), doubling that of PCIe 4.0. Leveraging a proprietary controller designed to support the latest PCIe standard, the PM1743 will deliver fast read and write speeds to accommodate the increasing performance requirements of data centers.

It will feature a sequential read speed of up to 13,000MB/s and a random read speed of 2,500,000 IO/s, offering 1.9x and 1.7x faster speeds over the previous PCIe 4.0-based products. Moreover, write speeds have been elevated, with a sequential write speed of 6,600MB/s and a random write speed of 250,000 IO/s, also delivering 1.7x and 1.9x faster speeds, respectively.

In addition, this SSD can provide improved power efficiency of up to 608MB/s per watt, which represents about a 30% boost over the previous gen. This is expected to lower server and data center operating costs, while also helping to reduce their carbon footprint.

Available in a variety of capacities from 1.92TB to 15.36TB, the PM1743 will be offered in the 2.5-inch form factor, as well as in a 3-inch EDSFF (E3.S) – an increasingly SSD form factor designed specifically for next-gen enterprise servers and data centers. Customers deploying 7.5mm EDSFF SSDs will be able to double the storage density in their systems, compared to when the 15mm 2.5-inch form factor is used. Coupled with signal integrity and thermal efficiency, the EDSFF is for most PCIe 5.0 enterprise solutions.

Furthermore, the PM1743 is expected to be the first PCIe 5.0 SSD with dual-port support, guaranteeing server operational stability and HA when a connection to one port fails.

Recently, the importance of data security has been growing stronger in the enterprise server market. To ensure that these needs are addressed, it will implement security features that were traditionally only available at the server level. By embedding a security processor and Root of Trust (RoT), the SSD will protect vs. security threats and data forgery to provide data confidentiality and integrity, while also enabling Secure Boot in server systems through attestation.

The company is delivering samples of the PM1743 to global chipset and server manufacturers for joint system development.

The firm plans to begin mass producing the PM1743 in 1FQ22, as it continues to foster a robust ecosystem for the PCIe 5.0 standard.

The PM1743 has been designated a CES 2022 Innovation Awards Honoree in the category of computer hardware and components.
