NAND flash memory is ubiquitous in everyday life today because its capacity has
continuously increased and cost has continuously decreased over decades. This positive …

Solid-state drives (SSDs) are used in a wide array of computer systems today, including in
datacenters and enterprise servers. As the I/O demands of these systems have increased …

Flash storage has become the mainstream destination for storage users. However, SSDs do
not always deliver the performance that users expect. The core culprit of flash performance …

Conventional error correction codes (ECCs), such as the commonly used BCH code, have
become increasingly inadequate for solid state drives (SSDs) as the capacity of NAND flash …

We present FEMU, a QEMU-based flash emulator for fostering future full-stack
software/hardware SSD research, with the following four" CASE" benefits. FEMU is cheap …

Indexes are special purpose data structures, designed to facilitate and speed up the access
to the contents of a file. Indexing has been actively and extensively investigated in DBMSes …

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 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 …

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 …

Storage applications leveraging Solid State Disk (SSD) technology are being widely
deployed in diverse computing systems. These applications accelerate system performance …
