Fast non-volatile memories (NVMs) will soon appear on the processor memory bus
alongside DRAM. The resulting hybrid memory systems will provide software with sub …

The Zoned Namespace (ZNS) interface represents a new division of functionality between
host software and flash-based SSDs. Current flash-based SSDs maintain the decades-old …

Flash memory based solid state drives (SSDs) have shown a great potential to change
storage infrastructure fundamentally through their high performance and low power. Most …

Over the last decade we have witnessed the relentless technological improvement in flash-
based solidstate drives (SSDs) and they have many advantages over hard disk drives …

Storage systems are designed and optimized relying on wisdom derived from analysis
studies of file-system and block-level workloads. However, while SSDs are becoming a …

Phase change memory (PCM) is an emerging memory technology with many attractive
features: it is non-volatile, byte-addressable, 2–4X denser than DRAM, and orders of …

Given the multilevel internal SSD parallelism at the different four levels: channel-level, chip-
level, die-level, and plane-level, how to exploit these levels of parallelism will directly and …

We examine the write endurance of USB flash drives using a range of approaches: chip-
level measurements, reverse engineering, timing analysis, whole-device endurance testing …

We introduce Skylight, a novel methodology that combines software and hardware
techniques to reverse engineer key properties of drive-managed Shingled Magnetic …

We perform a detailed vertical analysis of application performance atop a range of modern
file systems and SSD FTLs. We formalize the" unwritten contract" that clients of SSDs should …
