用固态电子存储芯片阵列而制成的硬盘由控制单元和存储单元(FLASH芯片、DRAM芯片)组成。固态硬盘在接口的规范和定义、功能及使用方法上与普通硬盘的完全相同在产品外形和尺寸上也完全与普通硬盘一致。被广泛应用于军事、车载、工控、视频监控、网络监控、网络终端、电力、医疗、航空、导航设备等领域。
优点读写速度快、防震抗摔性、低功耗、无噪音、工作温度范围大、轻便
缺点容量小、寿命有限、售价高 混合硬盘(hybrid harddriveHHD):
是既包含传统硬盘又有闪存(flashmemory)模块的大容量存储设备。闪存处理存储中写入或恢复最频繁的数据。很多公司开始提供这项技术的变体他们期望它会在高端系统中受到追捧尤其是在笔记本电脑和个人数字助理中。
相比传统硬盘混合硬盘(hybrid hard driveHHD)有很多
优点
1、应用中的数据存储与恢复更快如文字处理机
2、系统启动时间减少
3、功耗降低
4、生成热量减少
5、硬盘寿命延长
6、笔记本和PAD的电池寿命延长
7、工作噪声级别降低 缺点
1、硬盘中数据的寻道时间更长
2、硬盘的自旋变化更频繁
3、闪存模块处理失败不可能进行其中的数据恢复
4、系统的硬件总成本更高 传统硬盘(HDDHard Disk Drive的缩写)即硬盘驱动器的英文名。最基本的电脑存储器我们电脑中常说的电脑硬盘C盘、D盘为磁盘分区都属于硬盘驱动器。目前硬盘一般常见的磁盘容量为80G、128G、160G、256G、320G、500G、750G、1TB、2TB等等。硬盘按体积大小可分为3.5寸、2.5寸、1.8寸等;按转数可分为5400rpm/7200rpm/10000rpm等; SSD和HDD的比较
在过去10年中CPU的性能提升了150倍以上而传统硬盘才提升了1.5倍不到这种不均衡的发展极大的影响了整体性能的提升尤其在I/O方面而且SSD(固态硬盘)相比起传统硬盘它没有磁头马达磁盘等一系列的零件搭载NAND Flash芯片作为存储介质在运行速度功耗轻便等方面是传统硬盘所无法比拟的。 目前传统硬盘因为成本低廉等因素依然占据着硬盘市场的主要份额然而随着SSD的成本不断的降低技术不断提升与系统更好的支持等因素而且目前主流的笔记本电脑也都均配置SATA和mSATA接口包括目前的超极本(Ultrabook)也只有搭载SSD才可能实现“更轻更快更低功耗未来取代传统硬盘也是大势所趋。 现在你知道固态硬盘和混合硬盘的区别了吗
