New Delhi, India – August 8, 2025 – Sandisk today showcased a groundbreaking 256TB¹ NVMe™ enterprise SSD, setting a new benchmark in storage capacity, performance, and power efficiency. This innovation is powered by Sandisk’s new enterprise-grade UltraQLC™ platform, which combines BiCS8 QLC CBA NAND, custom controllers, and advanced system-level optimizations to deliver unprecedented capabilities.
Next-Generation Flash for the AI Era
As artificial intelligence transforms business workloads, flash storage must evolve to meet complex, data-intensive requirements. The SANDISK® 256TB¹ NVMe™ SSD, built on the UltraQLC™ platform, is purpose-designed for AI-driven workloads such as:
-
Data ingest and preparation
-
Fast AI data lakes
-
Large-scale hyperscale cloud applications
It delivers high performance, exceptional power efficiency, and improved total cost of ownership (TCO) for massive storage deployments.
Executive Perspective
“As we move into the next phase of the AI era, flash storage is becoming a critical enabler of intelligent, high-performance workloads,” said Khurram Ismail, Chief Product Officer at Sandisk. “Our UltraQLC™ platform is the culmination of years of work to create a flexible, robust architecture that achieves extraordinary capacities and maximum performance while maintaining efficiency. This allows us to meet AI demands at scale, enabling our customers to move faster, process more, and turn data into real innovation.”
Key Innovations in the UltraQLC™ Platform
The SANDISK® UltraQLC™ 256TB¹ NVMe™ SSD brings several industry-first capabilities to hyperscale flash storage, including:
-
Direct Write QLC – Eliminates SLC buffering by enabling power-loss-safe writes on the first pass.
-
BiCS8 2Tb QLC Die – Doubles storage density while maintaining compact die sizes.
-
UltraQLC™ Power Optimization – Dynamic Frequency Scaling boosts performance by up to 10% for the same power level² (projected).
-
Scalable Multi-Core Controller – Delivers high throughput and endurance at extreme capacities.
-
Data Retention (DR) Profile – Reduces DR recycles by up to 33%³ (projected), improving reliability, resilience, and energy efficiency.
