PCIe 6.0 SSDs Arrive for AI Data Centers
18 Feb
Summary
- Micron's new SSDs offer significantly faster read and write speeds.
- These drives are exclusively designed for AI data centers, not consumers.
- New SSDs promise higher transfer rates per watt and lower operational costs.
Micron has introduced the first SSDs based on the PCIe 6.0 standard, the 9650 series, primarily targeting AI data centers. These new drives deliver substantial performance gains, with sustained read speeds reaching 28Gbps and sequential writes up to 14Gbps. Compared to PCIe 5.0 alternatives, they offer up to 100% faster sustained reads and up to 40% faster write speeds, significantly improving random read and write performance as well.
The enhanced bandwidth of PCIe 6.0 is crucial for AI workloads, helping to reduce CPU cycle demands and latency during training and inferencing. While consumer adoption is still distant due to upcoming CPU and motherboard requirements, AI data centers are poised to leverage this technology for greater efficiency and reduced operational costs. The drives support both air- and liquid-cooled solutions, though higher heat output is expected.
Micron has conducted extensive interoperability testing to ensure the reliability of these high-speed drives. OEMs and AI data center customers will now begin validating them for real-world deployments. Although current consumer applications may not immediately benefit, future advancements in operating systems and developer optimization suggest that consumer-grade PCIe 6.0 SSDs could become relevant in the coming years.
