HBF High-Bandwidth Flash Faces Doubts Over Limited Use Cases

Discussions around HotChips 2026 suggest HBF's large capacity and low cost come with limited applicability—mainly sparse attention or expert parallelism—and clarify that read bandwidth can approach HBM while writes remain constrained, making energy efficiency more critical than cost.
