当用户执行数据读取操作时,传统硬盘每秒钟只能响应100-200次,而SSD硬盘可提高到每秒钟5000次,彻底消除延迟现象。4GBSSD磁盘可与目前的SATA、IDE硬盘搭配使用。
SSD硬盘介绍:SSD硬盘,广泛应用于工业、冗余存储等稳定性比较高的领域,SSD硬盘是用Flash加FPGA开发而成的,有以下特点: ● 持续读/写速度:Up to 60MB/s ● 44Pin IDE接口(2.5-inch),40Pin IDE接口(3.5-inch) ● 2.5-inch/3.5-inch的工业标准 ● 符合ATA-5标准,支持PIO0-4,UDMA0-4 ● Master/Slave跳线选择 ● 百万次的擦写周期 ● 容量:从2GB到128GB ● 10年的数据保持时间 ● 防震、防碰撞的金属外壳 ● 紧凑的设计,厚度仅为9.5mm ● 读写损耗均衡、坏块管理算法专利 ● 不稳定供电时,具有可靠的运行保证 ● 快速的初始化,固件可以现场升级 在可靠性方面有以下特点: ● 手动/自动的自诊断系统 ● 可选的掉电保护电路 ● EDC/ECC错误检测和错误纠正 ● SMART系统
