Samsung put out a few details on an upcoming product for Q2 2022 when we expect the next-generation server systems to start shipping in higher volumes. Specifically, the Samsung PM1743 is a new SSD designed for the EDSFF era and higher speeds and densities in servers.
Samsung PM1743 PCIe Gen5 E3.S 1T EDSFF SSD Teased
Previously, we saw that Samsung announced another drive. The Samsung PM9A3 PCIe Gen4 NVMe Data Center SSDs was released for PCIe Gen4 systems. What is interesting is the specs that Samsung shared about its next-gen drive.
Samsung says the PM1743 is a V6 TLC-based drive with 1 DWPD of write endurance. It is also a 1T form factor drive which means it is the single-width form factor. E3.S 1T drives are designed for up to 20-25W of power. The 2T drives are designed for up to 35-40W and the E3.L 1T drives are also designed for up to 40W. As a result, and given the pictures this is likely going to be a 20-25W drive.
Samsung says it is a PCIe Gen5 1×4 (single port) or 2×2 (dual port) drive and seems to be showing a high-level mechanical drawing of the next-generation SSD.
Overall, we know many EDSFF drives are coming. By 2025 most of the large vendors expect that in terms of capacity, EDSFF will capture around 50% of the total SSD market. Specifically though the transition is expected to mostly be a migration from 2.5″ to E1.S rather than 2.5″ to E3. That makes the Samsung PM1743 more of a niche drive than some of the E1.S offerings that we have been seeing.

In that piece we go into some of the details and show off E1.S and E3.S drives. We use a Kioxia XD6 labeled E3.S drive in that video but it appears to be the same form factor as the PM1743.
