放大图片 SSD电子盘即固态盘（Solid-state disk，SSD）也称电子硬盘，由控制单元（Controller）和存储单元（FlashIC）组成。由于固态盘没有普通硬盘的机械旋转装置，因而抗震性能极佳，同时工作温度范围很宽，扩展温度的固态盘可工作在-45℃～+85℃之间，所以被军事、车载、工控、视频监控、网络监控、网络终端、电力、医疗、航空、导航设备等对数据存储要求高的领域所重识，只因价格过于昂贵，目前还未能得到普及。
4GB SSD硬盘采用ATA接口，支持Ultra DMA Mode 4传输模式，同时支持微软的Ready Boost技术，可作为操作系统的高速读写缓存，实现系统和程序的加速。大大缓解用户目前在切换程序过程中的缓慢等待时间。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normalTable style="MARGIN: auto auto auto 0.5pt; BORDER-COLLAPSE: collapse; mso-table-layout-alt: fixed; mso-padding-alt: 0cm 0cm 0cm 0cm" cellSpacing=0 cellPadding=0 border=0>
