Samsung SSD Hits 28.4 GB/s, Needs Liquid Cooling
The PM1763 enterprise drive, announced but not yet shipping, uses PCIe 6.0 with full enterprise deployment expected in early 2027.
Updated on Nov. 5, 2026 in Semiconductors
Samsung Electronics has revealed technical specifications for its PM1763 enterprise solid-state drive, which uses the PCI Express 6.0 x4 interface. The drive is announced and has not yet shipped; mass production of its logic controllers is scheduled for late 2026.
Why it matters
The PM1763 moves enterprise storage toward PCIe 6.0, which doubles peak bandwidth over PCIe 5.0 storage devices and points to where data-center storage is heading. Its reliance on liquid cooling marks a shift away from air-cooled storage for sustained workloads.
Samsung's laboratory benchmark reports sustained sequential reads of 28.4 GB/s (28,400 MB/s) on the PCIe 6.0 x4 interface, roughly double PCIe 5.0 peak theoretical bandwidth. These are manufacturer-reported lab results rather than shipping-product measurements, and independent testing has not been reported.
The players
Samsung Electronics
South Korean semiconductor and memory manufacturer whose V-NAND flash stack and enterprise SSD lineup make it a leading supplier of data-center storage.
The details
The PM1763 uses PAM4 (Pulse Amplitude Modulation 4-Level) signaling, a method that encodes two bits per symbol instead of one, native to the PCIe 6.0 standard. PAM4 replaces the older NRZ (non-return-to-zero) approach and roughly doubles transmission efficiency per lane. Sustaining 28.4 GB/s generates heavy heat in the controller and the eighth-generation V-NAND flash stack, which is why the design requires active liquid-loop cooling blocks rather than passive or air-cooled setups.
Timeline
Late 2026: mass production of PM1763 logic controllers is scheduled.
Early 2027: full enterprise deployment is expected.
The Tech Race
The PM1763 positions Samsung on the PCIe 6.0 generation of enterprise storage ahead of broad deployment, with the drive's controller and flash stack built on its own V-NAND. The source does not name a specific competing product or rival roadmap for direct comparison.
Enterprise buyers planning data-center storage will face liquid-cooled requirements for sustained PM1763 workloads, which affects facility design. Pricing and availability dates for the drive have not been announced.
The takeaway
Watch for the late 2026 mass-production milestone for PM1763 logic controllers, which will show whether the 28.4 GB/s figure holds beyond laboratory conditions. Enterprise deployment expected in early 2027 will be the next test of the liquid-cooling requirement.
What happens next
Mass production of PM1763 logic controllers is scheduled for late 2026, and full enterprise deployment is expected in early 2027.
