Don't be a blockhead: zoned namespaces make work on conventional SSDs obsolete
Research on flash devices almost exclusively focuses on conventional SSDs, which expose
a block interface. Industry, however, has standardized and is adopting Zoned Namespaces …

IODA: A host/device co-design for strong predictability contract on modern flash storage
Predictable latency on flash storage is a long-pursuit goal, yet, unpredictability stays due to
the unavoidable disturbance from many well-known SSD internal activities. To combat this …
