Ensuring Data Survival on Solid-State Storage Devices

چکیده
The emergence of more reliable, often much faster solid-stage storage devices is revolutionizing most aspects of data storage technology. Here we address the impact of these new storage devices on the techniques used to ensure data survival. In particular, we show that the higher bandwidth-to-capacity ratios of the new Storage Class Memory devices will make selfadaptive storage solutions much more attractive.

Advanced Storage Systems 15/18-746: Project #2: Hybrid SSD/HDD/Cloud Storage System
In this project, you will build a file system, called CLOUDFS, to integrate into one system with a set of heterogeneous storage devices, particularly solid-state devices (SSDs), hard disk drives (HDDs) and cloud storage systems (Amazon S3, etc.). To ease development, this file system will be built using the “file system in user-space” (FUSE) API. CLOUDFS includes two parts: a core file system t...
متن کاملCharacterizing the Performance of Flash Memory Storage Devices and Its Impact on Algorithm Design
Initially used in digital audio players, digital cameras, mobile phones, and USB memory sticks, flash memory may become the dominant form of enduser storage in mobile computing, either completely replacing the magnetic hard disks or being an additional secondary storage. We study the design of algorithms and data structures that can exploit the flash memory devices better. For this, we characte...
متن کاملA New I/O Scheduler for Solid State Devices
Since the emergence of solid state devices onto the storage scene, improvements in capacity and price have brought them to the point where they are becoming a viable alternative to traditional magnetic storage for some applications. Current file system and device level I/O scheduler design is optimized for rotational magnetic hard disk drives. Since solid state devices have drastically differen...
متن کاملFRP: A Nonvolatile Memory Research Platform Targeting NAND Flash
In this paper, we introduce the Flash Research Platform (FRP), a non-volatile memory research platform that targets Solid State Storage (SSS) and NAND Flash research. We are developing the FRP because we believe that solid state storage devices such as Solid State Disks (SSDs) will be a ubiquitous persistent storage medium within 5 years for personal computers and servers. Solid state technolog...
متن کاملSolid State Drives: The Beginning of the End for Current Practice in Digital Forensic Recovery?
Digital evidence is increasingly relied upon in computer forensic examinations and legal proceedings in the modern courtroom. The primary storage technology used for digital information has remained constant over the last two decades, in the form of the magnetic disc. Consequently, investigative, forensic, and judicial procedures are well-established for magnetic disc storage devices (Carrier, ...
