Not All QLC Is Created Equal: Designing Flexible Architectures for NAND Diversity

Hyperscalers face increasingly complex challenges as they integrate diverse NAND media with modern filesystems across many demanding workloads. Meeting these challenges requires flexible, software-defined architectures that support mixed-mode operation, intelligent data placement, and workload-aware optimization. It also requires advanced performance metrics and analysis tools to enable rigorous evaluation, expose device-level tradeoffs, and predict failures earlier.
