A few days ago, PCI-SIG announced that the PCI Express 6.0 draft 0.71 specifications have been released, and plans to release the final version of the specification this year. Although the PCI Express standard is advancing very quickly, even for enterprise-level products, it has not officially entered the PCI Express 5.0 standard. For ordinary consumers, it is even more distant. At this stage, the market is still in the transition period from PCI Express 3.0 to PCI Express 4.0.
With the arrival of the first batch of enterprise-level products supporting the PCI Express 5.0 standard, such as Intel’s Sapphire Rapids processor and AMD’s EPYC processor with “Genoa” core, major manufacturers are also stepping up the development of related products. According to a report from
Serve The Home, Samsung has recently announced the preliminary details of enterprise-level solid-state drives using PCI Express 5.0 standard interfaces and plans to launch this product in the second quarter of 2022.
The
Samsung PM1743 solid-state drive will be based on a self-developed main control chip and the sixth-generation TLC V-NAND flash memory, which can withstand a full-disk write once a day and is designed for mixed workloads. It is equipped with a PCIe Gen5 x4 (single port) or dual x2 (dual port) interface, adopts E3.S 1T form factor (length and width are 111.5 mm × 31.5 mm respectively), theoretically the bandwidth of PCIe Gen5 can reach 15.7 GB/s. In any case, PM1743 is faster than PM9A3. The latter is a product designed for data center applications. It is one of Samsung’s fastest PCIe Gen 4 x4 solid-state drives, which can provide a continuous read speed of 6800 MB/s.
Most enterprise-class SSDs designed for mission-critical applications use a 2.5-inch form factor, using SAS or U.2 interfaces, and some use PCIe Gen3/Gen4 x8 interfaces. Samsung also plans to use the seventh-generation 176-layer TLC V-NAND flash memory for enterprise-level solid-state drives with PCI Express 5.0 standard interfaces, but no specific information has been announced.
