Micron has crossed a significant milestone with the 9650 series, the first PCIe Gen 6 NVMe SSD to transition from development to mass production. Designed for data centers where AI training and inference demand relentless data throughput, the 9650 isn’t just an incremental upgrade—it’s a leap forward in storage efficiency.
The drive leverages Micron’s in-house G9 TLC NAND, a custom SSD controller ASIC, and proprietary firmware, all validated over 18 months of ecosystem testing. This includes interoperability checks with high-port switches and retimers, ensuring compatibility with next-generation infrastructure. The result is a drive that pushes performance boundaries while maintaining power efficiency.
Performance That Redefines the Benchmark
The 9650’s sequential read speeds hit 28 GB/s—double the 14 GB/s offered by PCIe Gen 5 drives—and sequential writes reach 14 GB/s, a 40% improvement over its predecessor. Random read performance peaks at 5.5 million IOPS, while random writes hit 900,000 IOPS, representing 67% and 22% gains, respectively.
What sets the 9650 apart isn’t just raw speed, though. Micron highlights its efficiency: at a 25-watt power state, the drive delivers 1,120 MB/s per watt for sequential reads—twice the efficiency of Gen 5—and 560 MB/s per watt for writes, a 1.4x improvement. Random read efficiency jumps to 220 KIOPS per watt, 1.7 times higher than Gen 5, while random writes see a 1.2x boost to 36 KIOPS per watt.
Built for AI’s Insatiable Appetite
Data centers running large language models or retrieval-augmented generation pipelines need storage that can keep pace with GPU acceleration. The 9650 addresses this by supporting both air-cooled and liquid-cooled configurations, allowing operators to optimize for performance density in high-throughput environments. Early adopters include OEMs and AI-focused data center customers already qualifying the drive for deployment.
The SSD is available in E1.S and E3.S form factors, with the E1.S variant accommodating liquid cooling—a critical feature for AI clusters where thermal management is as important as speed.
A New Standard for Gen 6 Storage
Micron’s move into mass production of the 9650 signals a shift in the storage landscape. While PCIe Gen 6 has been on the horizon for years, the 9650 is the first to prove it can deliver on its promise at scale. For AI workloads, where data bottlenecks can stall training cycles, this could be a game-changer. The drive’s efficiency metrics suggest it won’t just replace Gen 5 SSDs—it will redefine what’s possible in high-performance storage.
With competitors like Samsung and SK hynix also pushing Gen 6 solutions, Micron’s early lead in production could influence adoption trends. Whether in hyperscale data centers or next-gen supercomputing, the 9650 sets a new benchmark for what storage can achieve.
