Micron announced the launch of its 245‑TB Micron 6600 ION SSD, the highest‑capacity commercial SSD available today. The drive delivers 245.76 TB of usable storage, uses Micron’s G9 QLC NAND, and reduces rack space by 82 % while cutting power consumption to roughly half that of comparable HDD deployments.
The 245‑TB capacity is achieved through a 4.5‑fold increase in density compared with previous Micron SSDs, and the G9 QLC NAND provides higher endurance and performance than earlier QLC generations. The result is a single drive that can replace dozens of traditional hard‑disk arrays, freeing valuable data‑center floor space and lowering cooling and power budgets.
The launch comes at a time when artificial‑intelligence workloads are driving unprecedented data‑growth in cloud and hyperscale environments. IDC forecasts that AI‑driven storage demand will outpace traditional workloads, and Micron’s new SSD directly addresses the need for higher density, lower power, and predictable performance that AI operators require.
While Kioxia has also shipped 245‑TB NVMe SSDs, Micron’s G9 QLC NAND is described as “at least one generation ahead of any competing QLC used in data‑center SSDs.” Micron’s product is therefore the first commercially available drive that combines the highest capacity with the most advanced NAND technology.
Micron’s broader financial performance underscores the strategic importance of the new drive. Fiscal Q1 2026 revenue reached $13.64 billion, and fiscal Q2 2026 revenue jumped to $23.86 billion, a 196 % year‑over‑year increase. Gross margin expanded to 74.4 % in Q2 from 56.0 % in Q1, driven by strong demand in the data‑center segment and the higher‑margin NAND business, which accounted for 21 % of total revenue in Q2.
Senior Vice President Jeremy Werner said, “AI workloads are driving massive growth in shared data, continuing the shift of data center storage share from HDDs toward SSDs. With 245TB in a single SSD, the Micron 6600 ION makes solid state storage the clear choice for modern data centers.” IDC Research Vice President Jeff Janukowicz added, “Rapid AI dataset growth is shifting storage economics from individual drives to rack‑level efficiency. Operators need more usable capacity per rack while staying within strict power and cooling constraints. Micron’s 245TB drives deliver the density required to scale AI data pipelines without increasing data center footprints. Predictable performance, energy efficiency and higher capacity are essential to building cost‑effective AI infrastructure.”
Micron’s Chairman, President and CEO Sanjay Mehrotra noted, “In fiscal Q1, Micron delivered record revenue and significant margin expansion at the company level and also in each of our business units.” He continued, “Our Q2 outlook reflects substantial records across revenue, gross margin, EPS, and free cash flow, and we anticipate our business performance to continue strengthening through fiscal 2026.” He added, “Micron set new records across revenue, gross margin, EPS, and free cash flow in fiscal Q2, driven by a strong demand environment, tight industry supply, and our strong execution, and we expect significant records again in fiscal Q3.”
Investors reacted positively to the announcement, reflecting confidence in Micron’s ability to meet the growing AI‑driven storage demand and its leadership in high‑capacity SSD technology.
