What happened
Micron presented G11 as its next NAND node, skipping G10 between G9 and G11 during an October 21 technology webinar.S1 The company plans wafer-on-wafer bonding, more than 400 layers, roughly twice G9's bit density, up to 1.5x its I/O speed and more than 25% lower data-transfer energy per bit, with a volume ramp scheduled for the second half of 2027.S1
Micron's roadmap places a 512TB ceiling on next-generation data center SSDs and identifies a high-IOPS class at 25 million to 100 million IOPS for small-block access.S1 The 512TB figure is a roadmap label rather than an announced product, and the source did not disclose an interface, cell type or date for it.S1 Micron's existing 245TB Micron 6600 ION SSD uses G9 QLC.S1
The company is also evaluating two AI-oriented NAND concepts: small-block, SLC-based storage for vector search, graph analytics and AI context, and TSV-stacked dies on a logic base die for model weights, long context and KV cache.S1 Micron has not named products, bandwidth figures or customers for either design.S1
| Metric | Reported value | Source |
|---|---|---|
| G11 layer count | More than 400 layers | S1 |
| Bit density versus G9 | 2x | S1 |
| I/O speed versus G9 | Up to 1.5x | S1 |
| Data-transfer energy per bit | More than 25% less | S1 |
| Potential SSD capacity | Up to 512TB | S1 |
| High-IOPS target | 25 million to 100 million IOPS | S1 |
Background timeline
- - Micron launched the G9 node in the 2650 client SSD.S1
- - StorageReview reviewed the 245TB Micron 6600 ION, a G9 QLC SSD.S1
- - StorageReview compared the 245TB Micron 6600 ION with hard drives.S1
- - CEO Sanjay Mehrotra said memory and storage supply-demand conditions would be much tighter in calendar 2027 and 2028 than in 2026.S1
- - Micron presented its G11 NAND roadmap during a technology webinar.S1
XAIPART take
Technical impact
XAIPART analysis: Wafer-on-wafer bonding may decouple memory-array fabrication from peripheral logic, which could improve manufacturability above 400 layers. XAIPART analysis Buyers should evaluate controller firmware, thermal behavior and endurance rather than treating G11's headline density and I/O gains as complete product specifications.
Market impact
XAIPART analysis: A 2H 2027 volume ramp leaves design teams time to qualify alternatives, but Micron's warning about constrained supply supports maintaining dual-source plans for E3.L and other high-capacity SSD positions. XAIPART analysis Lead times and allocation for 512TB-class drives cannot be quantified from the disclosed roadmap.
Action
XAIPART analysis: Record G11 as a future evaluation platform and request samples, validated power data and controller details when Micron releases them. XAIPART analysis Procurement teams should avoid treating the 512TB label as an orderable SKU until specifications and availability are published.
XAIPART Forecast
XAIPART analysis XAIPART expects Micron to disclose a production-ready G11 SSD with a capacity of at least 512TB by Q4 2027; if no such product is announced by 2027-12-31, this forecast is wrong.
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. This is a single-source roadmap report, and Micron has not disclosed a 512TB product specification, availability date, pricing or customer.
Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
