Micron is now shipping a 245 TB version of its Micron 6600 ION data center SSD, targeting rack-scale density gains for AI, cloud, enterprise, and hyperscale storage deployments. The company is pitching the drive for next-generation AI data lakes and cloud-scale file and object storage, where footprint, power, and cooling constraints increasingly shape storage architecture.
The 245 TB Micron 6600 ION is offered in U.2 and E3.L form factors. Micron says the E3.L configuration can cut the number of racks required for equivalent raw capacity by 82% versus HDD-based deployments, based on a comparison of 720 drives per 36U using 245.76 TB SSDs (176.9 PB per rack) versus 44 TB HDDs (31.7 PB per rack). For media, Micron lists the drive as built with its G9 QLC NAND.
On power, Micron rates the 245 TB SSD at up to 30 W peak. The company compares that to 44 TB HDDs at 10 W peak each (noting the HDD power figure is based on 32 TB/36 TB HDD peak power data), and concludes the SSD approach is “only half” the power of a comparable-capacity HDD deployment when scaled to equal raw capacity. In a separate 1 EB example, Micron states that 4,069 SSDs versus 22,727 HDDs would be required, and that an HDD deployment would require 1.9x more energy than 245 TB 6600 ION SSDs at maximum power over a year, yielding 921 MWh/year of energy saved under its assumptions.
For data center engineers, the interesting part isn’t just the headline capacity—it’s what quarter-petabyte SSDs do to design math. When capacity per drive jumps by multiples, you can change the number of enclosures, rack units, and ports you need to stand up a target PB/EB tier, which can reduce failure domains and day-two maintenance touches. But the practical tradeoffs still come down to whether the workload benefits from the SSD characteristics Micron is highlighting, and whether your constraints are floor space, power, cooling, or operational complexity.
Micron is also making performance and efficiency claims based on internal testing. In Micron lab tests comparing a single 245 TB SSD to an array of 16x 16 TB data center HDDs, the company reports “up to” 84x better energy efficiency, 8.6x faster AI preprocessing, 3.4x better ingest throughput, and up to 29x lower latency for AI extraction, transformation, and loading (ETL). For object storage, Micron cites MinIO testing using the Warp S3 benchmark with 4 MB objects, reporting up to 435x better throughput per watt, 96x faster time to first byte, and 58x better aggregate throughput versus the same style of HDD array.
“With 245TB in a single SSD, the Micron 6600 ION makes solid state storage the clear choice for modern data centers,” said Jeremy Werner, senior vice president and general manager of Micron’s Core Data Center Business Unit.
