Micron has a new capacity point for its 6600 ION NVMe SSD family, and this one is the eye-catcher. The company now has a 245.76TB version of the Micron 6600 ION, giving data center platforms a way to put almost a quarter petabyte of flash into a single SSD.
Micron 6600 ION 245TB SSD Announced
The Micron 6600 ION is the company’s capacity-focused PCIe Gen5 data center SSD line built with Micron G9 QLC NAND. The family already includes the 122.88TB E3.S drive, and the 245.76TB model moves that same basic idea into larger E3.L and U.2 options. The result is a drive aimed less at peak transactional performance and more at dense AI data lakes, hyperscale storage, analytics clusters, and other environments where capacity per rack and watts per terabyte matter.
Micron says the new 245.76TB drive delivers up to 13.7GB/s for sequential reads and 3.0GB/s for sequential writes, up to 1.78 million random read IOPS, and a maximum power rating of 30W. On its public product page, the company says the E3.S 122TB version can store over 2.4PB per 1U, while the E3.L 245TB version can reach over 3.9PB per 1U. Micron’s briefing material goes even further, showing a 36U rack comparison with up to 176.9PB using 245.76TB E3.L SSDs.
The bigger story here is not simply that a 245TB-class SSD exists. It is the EDSFF form factors that are making much denser storage shelves practical. Micron’s materials compare a 1EB deployment using 245.76TB E3.L SSDs against 44TB hard drives and show a 5.6x reduction in rack space, based on Micron’s 36U storage allocation assumptions. That is the pitch: fewer chassis, fewer racks, and less supporting infrastructure around the same dataset.
Micron is also positioning the drive around AI and object storage, which is common for the AI data centers, where this kind of drive is prevalent.
We previously covered the lower-capacity 6600 ION alongside Micron’s broader data center SSD lineup in our article on the Micron 9650, 6600 ION, and 7600 NVMe SSDs. We also covered prior ION generations, including the Micron 6550 ION 61.44TB PCIe Gen5 SSD and our Micron 6500 ION 30.72TB review. The jump from those capacities to 245TB is a reminder of how quickly QLC and EDSFF are changing the dense storage discussion.
Final Words
With the cost of modern SSDs, the Micron 6600 ION 245TB is not going to be the drive for every workload. Frankly, pricing pressure is weighing on even large AI cluster build-outs. At the same time, the density that solutions like this can provide is just awesome.
