Question · Q1 2026
Mehdi Hosseini requested an update on the UltraQLC 256 TB product, specifically regarding a tier one data center customer expected to ramp in the first half of the calendar year. He also asked if, assuming no new wafer capacity at the JV, the ramp of 128 TB drives mid-next year would lead to more bit allocation to these customers and an accelerated mix shift towards cloud.
Answer
Chairman and CEO David Goeckeler clarified that the 128T drives are currently under qualification with multiple customers, with ramping expected mid-next year, while the 256T drives are likely to hit the market mid to late next year. He confirmed that Sandisk is working with five hyperscalers across its enterprise SSD portfolio. Goeckeler stated that sequential growth in the data center portfolio is expected throughout fiscal year 2026, implying an exabyte shift in that direction. EVP and CFO Luis Visoso added that BiCS8 wafers contain significantly more bits, allowing for increased supply without new wafer production.
