Hard disk is widely used as a mass storage device, providing ability of rapid random access. Making use of the physical property of magnetic medium, hard disk provides nonvolatile and relative safe storage for data. 硬盘作为现阶段大容量的快速随机存储设备被广泛应用,它利用高密度磁介质来存储数据,具有断电不丢失数据的特性,这为数据的安全提供了较好的保证。
Magnetic Disk Storage Technology 磁盘存储技术
Semiconductors-based solid state disk is a new kind of high-performance and low-power storage device, which uses Flash disk as its storage media. The birth of Flash storage will gradually replace traditional magnetic disk storage. 基于半导体的以Flash为存储介质的存储器是一种高性能、低能耗的新兴存储设备,它的问世将逐渐取代以磁记录方式存储数据的硬盘。
Currently, the use of magnetic disk arrays to form the massive magnetic recording system has become an inevitable trend, and disk array-related technology has become a hot area of research and the mainstream technology for data storage. 目前,采用磁盘阵列来构成海量磁记录系统已成为必然趋势,磁盘阵列相关技术也成为研究的热点和数据存储的主流技术,磁盘阵列已成为一种重要的存储系统体系结构。
