Micron ships 245-TB data center SSD
Micron Technology’s 245-TB 6600 ION SSD boosts rack-scale storage density for data centers and AI infrastructure. Now shipping, the company describes it as the industry’s highest-capacity commercially available SSD. Built with Micron’s G9 QLC NAND in an E3.L form factor, it requires 82% fewer racks than equivalent HDD-based deployments, while reducing power and cooling needs for large-scale, data-intensive workloads.
Micron lab testing showed significant gains over HDD-based systems. For AI workloads, the 245-TB Micron 6600 ION SSD achieved up to 84 times better energy efficiency, 8.6 times faster preprocessing, and 29 times lower latency. For object storage, it delivered up to 435 times better throughput per watt and 96 times faster time to first byte.
For 1-EB deployments, Micron says the drive requires 1.9 times less energy than HDD-based systems, reducing annual CO2 emissions by 438 metric tons and saving 921 MWh of energy. The drive consumes up to 30 W of peak power, about half that of comparable-capacity HDD deployments, supporting data center sustainability initiatives.
The 245-TB Micron 6600 ION SSD will be on display at Dell Technologies World 2026, May 18–21, 2026.
