20 TB 的容量,带有重新设计的硬盘驱动器
重新设计硬盘驱动器以跟上数据增长,超大规模云、CSP、企业、智能视频监控合作伙伴、NAS厂商等需要存储解决方案来跟上数据生成的指数增长。对于大规模、具有成本效益的数据存储,硬盘驱动器仍然是一个战略选择。硬盘驱动器提供您存储大量数据时所需的容量、性能和可靠性,现在和将来。对硬盘驱动器技术的投资继续在支持全球数据增长方面发挥着中心作用。
Western Digital为优化驱动器的闪存记忆体开发了OptiNAND™技术,将领先的NAND闪存技术与我们品牌独有的硬盘驱动器集成在一起。Western Digital的硬盘驱动器在区域密度方面走在了前面,具备行业首创的能量辅助磁记录(EAMR)、三级致动器(TSA)、HelioSeal®,现在又加入了OptiNAND技术。更高的区域密度意味着更高的容量来满足存储挑战。
具有OptiNAND技术的20TB硬盘驱动器
OptiNAND将iNAND®(基于通用闪存存储(UFS)的嵌入式闪存驱动器(EFD))与传统的旋转介质结合起来,通过对算法和固件系统芯片(SoC)进行创新性更改。OptiNAND不是混合技术。该单元因优化固件算法而工作更智能,利用下载到iNAND的扩展元数据,实现更高的每英寸轨道数(TPI),从而导致更高的区域密度。
DC HC560 Ultrastar首次应用OptiNAND技术的能力,提供9盘平台上(每盘2.2TB)的无与伦比的20TB容量,采用CMR记录格式。
