Micron’s 6600 ION is a 245TB data center SSD now shipping, claiming 84x better energy efficiency for AI workloads versus alternatives.
Key Takeaways
The Micron 6600 ION ships in a U.2/E3.L form factor with 245TB capacity, targeting hyperscale and AI storage use cases.
Micron claims up to 84x better energy efficiency for AI workloads, which could meaningfully affect TCO at scale despite high upfront cost.
Sequential read reaches 13,700 MB/s; sequential write is only 2,700 MB/s, reflecting QLC NAND density tradeoffs.
The E3.L interface supports up to 16x PCIe lanes but the drive appears to use a 4x PCIe 5.0 equivalent configuration.
Hacker News Comment Review
Commenters flagged the 2,700 MB/s sequential write as a major limitation for most workloads; QLC IOPS (~40k) are slower than older SATA SSDs, making this drive sequential-access-only in practice.
Several commenters noted this form factor is effectively a high-density tape replacement for sequential backup/archival rather than a general-purpose NVMe drive.
Consumer SSD pricing was a recurring grievance: NVMe prices have regressed to 2021 levels after years of decline, and high-density portable consumer SSDs above 8TB remain largely unavailable at reasonable prices.
Notable Comments
@speedgoose: “I look forward to have my favourite hyperscaler grant me 1000 ‘premium’ IOPS per VM on this monster” – sharp dig at cloud IOPS throttling on dense drives.
@throwaway2037: Pulled the spec sheet confirming 4x PCIe 5.0 interface and flagged the write speed gap; notes E3.L theoretically supports 16x lanes.
