At the 2025 Global Memory Innovation Forum in Shenzhen, China, Samsung detailed its next-generation storage roadmap, confirming shipments of CXL 3.1 and PCIe 6.0 CMM-D products.
Kevin Yoo, CTO of Samsung’s Memory BU, shared a practical launch timeline:
- PM1763 Gen 6 SSD – Arriving in early 2026, offering 2× the performance of its predecessor while maintaining ~25W power consumption.
- 256 TB PCIe Gen 5 SSD – Targeted for 2026, with enterprise and AI applications in mind.
- 512 TB PCIe Gen 6 SSD (1T EDSFF format) – Planned for 2027, doubling capacity over the Gen 5 drives.
- Seventh-generation Z-NAND with GIDS (memory-class storage) – Scheduled for 2026, bringing ultra-low latency for specialized workloads.
Samsung first teased its PM1763 256 TB SSD in 2023, followed by a working prototype at the Future of Memory Storage 2025 event. The drive features a redesigned capacitor, controller, and DRAM layout, optimized for cooling and efficiency—critical factors in handling such extreme capacities.
High-capacity SSDs are increasingly sought after by AI labs, where training models require massive datasets. Samsung’s roadmap suggests a steady march toward scaling both capacity and performance while tackling power and thermal challenges.
