SSDs are now increasingly being adopted as primary nonvolatile storage in diverse
domains. The internal caches in the SSDs boost SSD performance, lifetime, and robustness …

Multi-streamed SSDs can significantly improve both the performance and lifetime of flash-
based SSDs when their streams are properly managed. However, existing stream …

Most flash-based solid-state drives (SSDs) adopt an onboard dynamic random access
memory (DRAM) to buffer hot write data. Then, the write or overwrite operations can be …

This article proposes a pattern-based prefetching scheme with the support of adaptive cache
management, at the flash translation layer of solid-state drives (SSDs). It works inside of …

This article proposes a low I/O intensity-aware scheduling scheme on garbage collection
(GC) in SSDs for minimizing the I/O long-tail latency to ensure I/O responsiveness. The basic …

Garbage collection (GC) and resource contention on I/O buses (channels) are among the
critical bottlenecks in solid-state drives (SSDs) that cannot be easily hidden. Most existing …

The write constraints of Multi-Level Cell (MLC) NAND flash memory make most of the
existing flash translation layer (FTL) schemes inefficient or inapplicable. In this article, we …

With the explosive growth of data volume and great improvement in flash technologies, SSD-
based In-Storage Computing (ISC) is becoming one of the most important means to …

This paper proposes an SSD-inside data prefetching scheme, which has features of OS-
dependence and use transparency. To be specific, it first mines frequent block access …

The read/write interference problem of flash storage remains a critical concern under
workloads with a mixture of read and write requests. To significantly improve the read …
