随着1GHz CPU的推出,个人电脑已进入千兆赫兹时代,电脑的运行速度更快了,同时如内存、显卡等相关设备的速度也都在大幅提升。但目前硬盘却还停留在ATA/66上,其最大外部数据率只有66MB/s,这严重影响着电脑系统的整体性能,可以说现在硬盘已成为个人电脑整体系统性能的瓶颈。基于这个考虑,各大硬盘厂商联合推出了ATA/100标准。新一代硬盘传输接口硬盘内部数据传输率的限制使得硬盘不能同时处理太多的数据。这样数据在硬盘的高速缓存中不得不排成队列等待硬盘的读写,这显然就降低了系统性能。解决此瓶颈的一个方法,看上去似乎很简单——即增加硬盘的数据缓存,高速数据缓存能使数据在结束传输前存储在高速的缓存中。这种方法能从某些方面缓解当务之急,但却无法从根本上解决问题,因为如果想更多缓解硬盘的
With the introduction of the 1GHz CPU, personal computers have entered the era of gigahertz, and computers have been operating faster. At the same time, the speeds of related devices such as memory and graphics cards have also increased dramatically. However, the current hard drive still stays on the ATA/66. Its maximum external data rate is only 66MB/s, which seriously affects the overall performance of the computer system. It can be said that the hard drive has now become the bottleneck of the overall system performance of the personal computer. Based on this consideration, major hard disk manufacturers jointly launched the ATA/100 standard. The limitation of the internal data transmission rate of a new generation of hard disk transmission interface hard disk can not handle too much data at the same time. This data has to be queued up for reading and writing by the hard disk in the hard disk cache, which obviously reduces system performance. One way to solve this bottleneck seems simple: increase the hard disk’s data cache, and the high-speed data cache enables data to be stored in the high-speed cache before the end of the transfer. This method can alleviate some of the top priorities, but it cannot solve the problem fundamentally because if you want to ease the hard disk
