Micron 6600 ION — World's Largest 245TB PCIe Gen5 QLC NVMe SSD

Specifications

Overview

The Micron 6600 ION redefines what's possible in data center storage density. As the world's highest-capacity SSD with 245.76TB of usable storage in a single drive, it enables hyperscale and AI data centers to pack over 2.4 petabytes of flash storage into a single 1U server — delivering up to 5.6× the capacity per rack of high-capacity HDDs while consuming far less power and cooling. Built on Micron's advanced G9 QLC NAND with six-plane architecture, the 6600 ION combines quarter-petabyte capacity with PCIe Gen5 performance, making it the definitive choice for AI data lakes, cloud-scale object storage, and capacity-intensive analytics workloads.

The 6600 ION family spans 30.72TB to 245.76TB across U.2, E3.S, and E3.L form factors, giving data center architects unprecedented flexibility to balance density, performance, and cost. The flagship 245.76TB E3.L model requires 82% fewer racks to achieve equivalent raw storage capacity compared to HDD-based deployments, dramatically simplifying infrastructure while reducing failure points and maintenance overhead.

Key Benefits

World's Largest SSD: 245.76TB usable capacity in a single E3.L drive — a milestone that shifts the storage density equation decisively in favor of all-flash data centers. Micron G9 QLC NAND: At least one generation ahead of competing QLC used in data center SSDs, G9 QLC delivers the reliability and performance required for exascale AI and cloud infrastructure. Rack-Level Economics: 5.6× more capacity per rack than HDDs, with 82% fewer racks needed for equivalent raw capacity — slashing power, cooling, and floor space costs. PCIe Gen5 Performance: 14GB/s sequential reads and 2M IOPS random read ensure the massive capacity is served with sufficient bandwidth for AI data pipelines and analytics clusters. Flexible Form Factors: U.2 (15mm) for legacy compatibility, E3.S 1T for high-density 1U/2U servers, and E3.L for maximum capacity per drive — choose the right density for your architecture.
