Micron 9650 SSD: The world’s first PCIe Gen6 data center SSD
The unmatched 28 GB/s performance of the 9650 SSD dramatically accelerates AI training and inference workloads. During inference, high throughput and ultralow latency are essential to enable real-time data access for large models, such as enterprise agents with extended context windows and retrieval-augmented generation pipelines. The 9650 offers superior performance per watt compared to Gen5 SSDs, achieving up to 25% and 67% better storage energy efficiency for random writes and reads, respectively. The reduction in power consumption and carbon emissions allows data centers to meet sustainability goals while enhancing performance.2
“With up to 5.5 million IOPS for random reads, the Micron 9650 is purpose-built for AI pipelines' high-throughput, low-latency demands. This product helps ensure GPUs remain continuously fed with data, minimizing idle cycles and maximizing system efficiency. Combined with Dell’s advanced server architecture, this innovation empowers enterprises to unlock new levels of performance and insight,” said
“Advanced AI reasoning workloads require agents to swiftly access massive volumes of business and internet data,” said
Micron 6600 ION SSD: Massive density with the best-in-class space efficiency for AI data lakes
The Micron 6600 ION SSD delivers breakthrough scalability featuring up to 245TBs in a single drive, enabling hyperscale and enterprise data centers to consolidate server infrastructure and build massive AI data lakes — all while reducing storage footprint, energy and carbon emissions. This offering increases storage density up to 67% over the competition and delivers over 88PB per rack using servers,4 drastically reducing TCO.
“With Supermicro’s broadest selection of Petascale storage optimized servers supporting up to 36 E3.S SSDs, the Micron 6600 ION enables up to 4.42PB per 2U server delivering the highest density and power efficiency for large capacity AI workloads,” said
“The Micron 6600 ION is a game-changer for AI infrastructure, delivering exceptional capacity and performance that enables WEKA customers to manage and process larger datasets with less infrastructure and lower energy use,” said
Micron 7600 SSD: Leading performance for AI inference and mixed workloads
The 7600 PCIe Gen5 SSD offers class-leading performance,6 low latency and high-reliability QoS to support predictable, lightning-fast responsiveness for demanding data center workloads like AI transformation, training and inference. Capable of delivering industry-best sub-1 millisecond latency on the taxing RocksDB workload, the 7600 SSD is ideal for workloads where response time is critical. The 7600 SSD provides the right balance of affordability, performance and predictable latency for most data center workloads including AI.
Random read | Random read while writing | |
Maximum performance | Up to 21% higher | Up to 23% higher |
99thpercentile latency | Up to 59% better | Up to 76% better |
Energy efficiency | Up to 78% better | Up to 79% better |
“At CoreWeave, we're relentlessly focused on pushing the boundaries of performance and helping our customers maximize their infrastructure efficiency,” said
Micron's vertical integration ensures that each of these SSDs is designed and manufactured with a Micron controller, G9 NAND, DRAM, firmware and manufacturing processes. This integration helps provide exceptional quality and a more reliable, secure supply chain. Additionally, key security features — including hardware root of trust, SPDM 1.2 (attestation) for identity authentication and firmware verification, CNSA 2.0 dual signed PKI/LMS firmware binary, self-encrypting drive (SED) and Micron Secure Execution Environment8 — help secure data. OCP 2.6 support is available for the Micron 9650 and 6600 ION SSDs, and the 7600 SSD utilizes OCP 2.5 support.9
Availability
The 9650 and 7600 SSD samples are shipping now to customers. The 9650 is offered in E3.S and E1.S 9.5mm and 15mm form factors with air-cooled and liquid-cooled options. The 7600 SSD is available in multiple form factors, including E3.S, U.2 and E1.S with air-cooled heat sink options. The 6600 ION 122TB SSD samples are shipping later in the third quarter of calendar year 2025 in E3.S and U.2 form factors. The 245TB SSD version of the 6600 ION SSD is planned to be available in the first half of calendar year 2026.

1 At the time of announcement, no other Gen6 competitive SSDs are available that can provide the same or better performance as the Micron 9650 Gen6 SSD. The 9650 has two times the sequential read performance of the previous-generation 9550. Additionally, the Micron 6600 ION currently provides the highest-capacity solution available in a rack comparison using Micron E3.S drives: 20 SSDs per 1U x 36 servers (36U) x 122TB equals 88.5PB versus similar competitive U.2 form factor SSDs with 24 SSDs per 2U x 18 servers (36U) x 122TB equaling 53PB, leaving 6U for other equipment in each rack. The Micron 7600 SSD has the lowest latency based on competitive testing in Micron labs and has the lowest sub-1ms latency up to QD128 based on RocksDB testing in Micron labs with available drives, per footnote 5.
2 The 9650 has improved energy efficiency with two times the sequential read performance of the 9550 SSD, Micron’s previous-generation drive, with the same 25W maximum power.
