Samsung has released some preliminary details about its enterprise-class SSD with PCIe 5.0 x4 interface.These drives will provide E3.S 1T form factor within a year, just in time to catch up with the first enterprise platform that supports PCIe 5.0, such as AMD’s EPYC Genoa And Intel’s Sapphire Rapids,enter the market.
According to reports, Samsung’s PM1743 solid-state drive will be based on the company’s proprietary controller and the 6th-generation TLC V-NAND memory For homeThe SSD is rated to write at most one drive (1 DWPD) per date and is designed for mixed workloads.
Samsung PM1743 drive will be equipped with PCIe Gen 5 x4 (single port) or dual x2 (dual port) interface, and adopt E3.S 1T form factor (111.5 mm × 31.5 mm (length × width)) to increase the storage density of the server, and the performance of PM1743 There is no news, but the theoretical peak throughput of the PCIe 5.0 x4 interface is about 15.7 GB/s.
In any case, PM1743 should be faster than PM9A3 (designed for data center applications and one of Samsung’s fastest PCIe 4.04 x4 SSDs), which provides sequential read speeds of up to 6800. As for power consumption, an E3.S 1T driver can consume up to 25W of power.
Today, most SSDs are designed for enterprise and mission-critical applications (including Those from Samsung) It adopts a 2.5-inch form factor with SAS or U.2 interface. At the same time, some drives also adopt the form of add-on cards and use PCIe 3.0/4.0 x8 interface.versus EDSFF E3 In terms of form factor, Samsung and other SSD manufacturers will be able to increase the capacity of their drives and make the storage density of next-generation servers running AMD Genoa and Intel Sapphire Rapids processors higher.
It’s worth noting that Samsung plans to use its 7th generation 176-layer V-NAND memory for its PCIe Gen 5 SSD specifically designed for client PCs, But has not yet released an announcement about availability.
