245TB Micron 6600 ION Data Center SSD Now Shipping
Micron’s new 245TB data center SSD showcases how aggressively storage density and energy efficiency are scaling, enabling petabytes per rack and making SSDs far more attractive than HDDs for large AI and database workloads. Commenters highlight technical trade-offs such as QLC endurance, relatively slow sustained writes, and cooling in dense deployments, while also noting that hyperscalers will gladly pay for “enterprise” features and density. At the same time, many are frustrated that AI-driven demand and constrained fab capacity have pushed SSD and HDD prices sharply higher for consumers, reversing years of falling storage costs.
Access and Availability of the Press Release
- Some users hit “Access Denied” on Micron’s site, likely due to Akamai/CDN blocking or IP blocklists.
- Others report no issues; archived copies and PDFs are shared as workarounds.
Form Factor, Cooling, and Power
- Drive is E3.L / U.2-like “2.5-inch” enterprise form factor, up to 15mm height.
- Estimated 30W TDP; likely multiple PCBs with NAND on both sides, thermally bonded to the chassis.
- Density implies heavy forced-air cooling in packed servers, but 30W per 245TB is seen as excellent.
Capacity, Density, and Use Cases
- Main value: extreme density and power efficiency, not peak speed.
- Enables ~1PB in 4 drives in 1U; entire racks can reach tens of PB, changing database and storage-node sizing.
- Hyperscalers are expected to deploy hundreds of thousands of such drives for AI training data, model weights, and large datasets.
Performance and QLC NAND Trade‑offs
- Uses QLC NAND. Product brief lists ~13.7 GB/s sequential read and ~2.7–3 GB/s sequential write.
- Sustained write speed is viewed as “weak” compared to consumer SSD peaks, but defenders note consumer drives rely on fragile caching and burst behavior.
- Random IOPS (~40k at 4KB) are lower than many SATA/NVMe SSDs; drive is seen as optimized for large sequential workloads.
Endurance and Data Retention
- Endurance is advertised in DWPD terms (~1 DWPD mentioned, others infer variants). Some consider DWPD marketing-speak without full context.
- Concerns about QLC retention and unsuitability for long‑term unpowered cold storage; others argue datacenter workloads refresh data and use redundancy, so retention beyond a year or two unpowered is less relevant.
Pricing and “Enterprise” Premium
- Speculative pricing ranges from ~$80k–90k per drive, with prior 122TB enterprise SSDs cited around $40k.
- Enterprise SSDs from major vendors show extreme markups (examples of several thousand dollars for 3–4TB).
- Explanations for the premium: density, power efficiency, endurance via spare capacity, sustained performance, PCIe-based form factor, power‑loss protection, out‑of‑band management, and simple “enterprise” price elasticity.
Impact on Consumer Storage and Market Dynamics
- Multiple comments lament rising SSD/HDD prices and stalled consumer capacity growth, blaming AI demand.
- Debate over whether this is normal supply–demand cyclicality, cartel‑like behavior, or broader “market failure.”
- Consensus that AI datacenter demand is currently absorbing much of the NAND supply, keeping large consumer SSDs expensive.
