Revolutionary Tech Under the Hood
What makes this SSD special? Direct Write QLC eliminates traditional SLC buffering, enabling power-loss safe writes on the first pass. The BiCS8 2Tb QLC die doubles storage density while maintaining compact sizes, and Dynamic Frequency Scaling optimizes power consumption for maximum efficiency.
“As we move into the next phase of the AI era, flash storage is becoming a critical enabler,” explains Khurram Ismail, Chief Product Officer at SanDisk. The numbers back this up – data retention cycles are reduced by up to 33%, improving reliability while decreasing power consumption.
Impact on Enterprise Storage
This isn’t just about bragging rights. For hyperscale cloud providers and AI companies processing massive datasets, the UltraQLC™ platform offers a compelling total cost of ownership story. Lower latency, higher bandwidth, and greater reliability mean businesses can process more data faster.
The enterprise SSD market has been waiting for this kind of breakthrough, especially as AI workloads continue growing exponentially.
