Micron's 245TB SSD Makes Rack Power a Storage Design Metric

Micron's 6600 ION places 245TB of QLC NAND in one enterprise SSD, and StorageReview's analysis frames its value around data-center power and floor space rather than raw capacity alone. In the publication's test configuration, one drive replaced eight 30TB nearline hard drives. The SSD system consumed 170.2W during sequential writes, compared with 173.5W for the hard-drive configuration at idle. StorageReview estimates that replacing disk with flash at exabyte scale could reduce a best-case footprint from 22 racks to six and free enough power from fewer than three racks of drives to operate a GB200 NVL72. The figures are workload-specific lab measurements, but they illustrate why ultra-dense QLC flash is becoming an AI-infrastructure planning tool.
