Communicating by using information technology in various ways produces big amounts of
data. Such data requires processing and storage. The cloud is an online storage model …

In this paper, we comprehensively investigate the file fragmentation problem on mobile flash
storage. From our evaluation study with real Android smartphones, we observed two …

Persistent byte-addressable memory (PM) is poised to become prevalent in future computer
systems. PMs are significantly faster than disk storage, and accesses to PMs are governed …

Duplicate writes are prevalent in diverse storage systems, originating from data duplication,
journaling, and data relocations, etc. As flash-based SSDs have been widely deployed …

Recent advances in flash memory technology have reduced the cost-per-bit of flash storage
devices such as solid-state drives (SSDs), thereby enabling the development of large …

We argue that wear leveling in SSDs does more harm than good under modern settings
where the endurance limit is in the hundreds. To support this claim, we evaluate existing …

Recent advances in flash memory technology have reduced the cost-per-bit of flash storage
devices such as solid-state drives (SSDs), thereby enabling the development of large …

We present the design and implementation of a capacity-variant storage system (CVSS) for
flash-based solid-state drives (SSDs). CVSS aims to maintain high performance throughout …

Every database engine runs on top of an operating system in the host, strictly separated with
the storage. This more-than-half-century-old IHDE (In-Host-Database-Engine) architecture …

The lightweight codebase of SQLite was helpful in making it become the de-facto standard
database in most mobile devices, but, at the same time, forced it to take less-complicated …
