Samsung has just unveiled its PCIe 5.0 SSDs that are targeted towards the Enterprise segment. The announcement has been made just in time as platforms supporting PCIe 5.0 such as AMD’s EPYC Genoa and Sapphire Rapids are on their way to hit the market.
The SSDs are expected to feature an E3.S form factor and several other performance upgrades. So without further ado, let’s jump into a detailed spec breakdown of Samsung’s upcoming PCIe 5.0 SSDs.
Features & Specifications:
As mentioned earlier, the SSDs will have an E3.S 1T form factor which is relatively compact and more power-efficient compared to its larger counterparts. According to “servethehome’’, this SSD will be based on Samsung’s proprietary controller and 6th Gen TLC V-NAND memory profile. Designed for mixed workloads, this SSD will be capable of 1 drive writes daily.
As announced by Samsung, the PM1743 will feature a single port PCIe Gen 5 x4 or a dual-port interface for higher storage density in servers.
PM9A3 Vs PM1743:
Although there is no news about PM1743’s performance speed, we are expecting to see benchmarks higher than the PM9A3’s 6800 MBps read speed. The maximum sequential throughput of PCIe 5.0 x 4 interface is 15.7 GB/s which is more than double of the PM9A3 Gen 4 SSD.
In the current SSD market, most enterprise-grade SSDs use SAS or U.2 interfaces in a 2.5-inch form factor. Other drives use the PCIe 3.0 or 4.0 x8 interface as add-in cards. The EDSFF E3 form factor will enable Samsung and other SSD manufacturers to increase drive capacities and enable next-generation servers such as AMD’s Genoa and Sapphire Rapids processors to have higher storage density. The PM1743 is expected to arrive in Quarter 2 of 2022.
As for client PCs, no official announcement has been made by Samsung about its availability. Though Samsung has a plan for using the 7th Generation V-NAND memory layout for the PCIe 5.0 SSDs in the upcoming future.
