Samsung releases PM1743 PCIe 5.0 SSD: read speed of up to 13,000 MB/s
Samsung announced that it will launch a high-performance PCIe 5.0 SSD for enterprise server platforms, model PM1743. Samsung said that the data transfer speed of the new PCIe 5.0 SSD is nearly twice that of the previous generation product, and it has better energy consumption performance, which will help reduce the operating cost of the server. Samsung is currently evaluating with chipset and server manufacturers to promote the transition of future servers to PCIe 5.0 interfaces.
PM1743, as a high-performance SSD used in servers, is based on a self-developed master chip, combining PCIe 5.0 interface and Samsung’s sixth-generation V-NAND technology flash memory. Its sequential read speed is 13 GB/s, sequential write speed is 6.6 GB/s, random read is 2500K IOPS, random write is 250K IOPS. The performance is 1.7 to 1.9 times that of the previous generation using PCIe 4.0 SSD, which allows server manufacturers using PM1743 to enjoy better performance. At the same time, PM1743 achieves a transmission efficiency of 608 MB/s per watt. Compared with the previous generation product, the energy consumption performance is improved by about 30%, which means that the cost of data center deployment and operation can be reduced, and carbon emissions can be reduced.
Samsung PM1743 PCIe 5.0 SSD has two forms of 2.5-inch and 3-inch EDSFF (E3.S), the capacity starts from 1.92 TB, and the maximum can reach 15.36 TB. It is understood that the EDSFF form factor has higher power and better signal integrity, allowing PCIe 5.0 SSDs to achieve higher performance indicators. In the future, enterprise-level SSDs will gradually transition to EDSFF form. PM1743 should be the industry’s first PCIe 5.0 SSD that supports dual ports. When one port fails to connect, it can ensure the stability and reliability of the server.
At present, Samsung has provided samples of PM1743 to partners and plans to start mass production in the first quarter of 2022.
