Best-Fit ApplicationsStorage-hungry business applications Storage area networks (SAN) and network attached storage (NAS)Maximum-capacity entry-level servers and blade serversRich media content storageEnterprise backup and restore—D2D,virtual tapeCloud computingThe Seagate ® Exos ™ 7E2000 enterprise hard drives can store large amounts of data without using a ton of system space—up to 2000GB in a compact 2.5-inch form factor. Exos 7E2000 provides the density, low power consumption and data integrity needed in traditional data centers and the cloud.Trusted Bulk Data Storage in a Small Data Center FootprintExos 7E2000 drives optimize your data center footprint in a proven 2.5-inch form factor forinfrastructures requiring highly reliable access to bulk data. Conventional magnetic recording (CMR)technology helps Exos 7E2000 catalyze the datasphere, enabling data center architects and ITprofessionals to deliver trusted performance, rock-solid reliability and ironclad security for demanding 24×7 operations. A 2M-hr. MTBF rating with supported workloads of 550TB/year, dense data storage and low power consumption help you meet your storage SLAs while lowering TCO.Significant Hard Drive Power SavingsExos 7E2000 drives ensure data confidence with a reliable, low-power platform for efficient bulkstorage operations, even in harsh data center environments. Exos 7E2000 helps reduce per-gigabyte cooling and energy costs by packing high capacities into an SFF, low-power consumption drive.Included PowerChoice ™ technology empowers IT organizations to tailor systems for optimalperformance and power consumption, resulting in power savings of up to 35% over traditional 3.5-inch drives, and potentially operating as low as 1.1 watts when idle.Enhanced Enterprise Reliability, Data Protection and SecurityExos 7E2000 security features help protect data where it lives—on the drive. Exos 7E2000 drives help prevent unauthorized access and safeguard stored data with security levels that include SecureDownloads & Diagnostics, TCG-compliant Self-Encrypting Drive and government-grade FIPS tamper-resistent hard drive.1 Seagate Secure ™ drives simplify drive repurposing and disposal, help protect data-at-rest, and comply with corporate and federal data security mandates.1 Self-Encrypting Drives (SED) and FIPS 140-2 Validated drives are not available in all models or countries. May require TCG-compliant host or controller support. Instant Secure Erase (ISE) functionality meets the ISO/IEC 27040 and NIST 800-88 guidelines for complete and authoritative drive sanitization.4K Native5xx EmulationCapacity2TB1TB2TB1TB Standard Model Numbers ST2000NX0263ST1000NX0323ST2000NX0273ST1000NX0333 Seagate Secure™ Model1ST2000NX0323ST1000NX0363ST2000NX0343ST1000NX0373 Seagate Secure SED-FIPS Model1ST2000NX0333—ST2000NX0353—Interface12 Gb/s SAS12 Gb/s SAS12 Gb/s SAS12 Gb/s SAS PowerChoice™ Technology Yes Yes Yes Yes Protection Information Yes Yes Yes YesLow Halogen Yes Yes Yes YesSeagate RAID Rebuild®Yes Yes Yes YesMTBF2,000,000hr2,000,000hr2,000,000hr2,000,000hr Reliability Rating @ Full 24×7 Operation (AFR)0.44%0.44%0.44%0.44% Nonrecoverable Read Errors per Bits Read, Max 1 sector per 10E15 1 sector per 10E15 1 sector per 10E15 1 sector per 10E15 Power-On Hours per Year (24×7)8760876087608760Sector Size (Bytes per Logical Sector)4K4K5xx5xxLimited Warranty (years)5555Spindle Speed (RPM)7200RPM7200RPM7200RPM7200RPM Cache, Multisegmented (MB)128128128128Interface Access Speed (Gb/s)12.0, 6.0, 3.012.0, 6.0, 3.012.0, 6.0, 3.012.0, 6.0, 3.0 Max.

希捷网络存储硬盘选择指南说明书

网络存储硬盘选择指南营销快报希捷网络存储硬盘比较为网络存储应用选择正确的硬盘时应考虑三个重要因素:应用中的硬盘数、与所涉及工作负载相关的硬盘的可靠性和可用的安全特性。
希捷提供多款硬盘以支持网络存储,从小型家庭网络存储到大型企业阵列:希捷网络存储硬盘、希捷企业级 3.5 寸高效盘和希捷企业级 3.5 寸海量盘。
如需网络存储硬盘与台式机硬盘间差异的信息,请阅读网络存储与台式机:针对网络存储应用评估硬盘 (MB633)。
务必知晓将要用于网络存储阵列的硬盘数量,以帮助确保硬盘在应对抗振级别的同时仍能提供预期的性能。
计量方法有三。
一,硬盘如何减振。
双平面平衡等特性可将在多硬盘环境中会被放大而影响可靠性的硬盘振动降至最小。
二,旋转振动 (RV) 感应器可帮助将系统振动的影响降至最低。
感应到振动增加时,硬盘会跨硬盘机架进行分散。
如此一来,实现最大稳定性,从而改善性能和可靠性。
建议具有五个硬盘以上的系统使用旋转振动感应器。
最后,顶盖附加式 (TCA) 马达通过提高对机柜旋转振动和线性振动的容错,在企业环境中提供更高性能。
网络存储硬盘选择指南硬盘工作负载也会影响性能和可靠性。
例如,由录制电视节目或经由云或类似服务中继数据而产生 24×7 数据读取和写入的硬盘与个人电脑中硬盘的可靠性指标是不同的。
还要考虑硬盘的用例。
录制电视节目对硬盘而言是更有序或可预测的工作负载,因为视频是先录制而后按请求进行播放的。
随机工作负载则更像在线零售商店,例如 eBay ,其数据是随着人们发布要出售的商品、进行购买或浏览库存而随机写入和读取硬盘。
这是不可预测的,对硬盘而言要求更高。
最后,硬盘接口会影响可靠性。
企业级硬盘提供 SAS 接口,可借助双路径数据流实现更好的硬盘性能和更高的数据完整性。
设计硬盘并针对目标工作负载衡量硬盘时会考虑所有这些环境因素。
安全性特性,例如希捷快速安全擦除 (ISE) 和自加密硬盘 (SED),可为具有加密需求的网络存储环境增强安全性和性能。

全天候运行的保障——希捷酷狼_14TB_硬盘

将硬盘按照用途划分,以不同的规格提供最适合相关用途的产品是目前硬盘厂商常用的方法,在希捷的产品线中,酷狼(IronWolf)是针对网络存储设备推出的产品。
在其超大容量型号中,更是使用了不次于PC产品的7200RPM转速和256MB缓存设计,因此性能更加出色,而其7×24小时的使用能力很适合网咖服务器,还享有3年有限质保,高端产品酷狼Pro的质保时间则长达5年。
在实际测试中,其格式化后的实际容量为12.7TB,平均读写速度为204MB/s左右,最大传输速度为265.6MB/s左右,突发读取速度可达到300MB/s以上,随机存取则分别在180IOPS和60IOPS左右,完全能满足网咖服务器的需求。
希捷的NAS硬盘之所以被命名为酷狼,当然说明了它不仅快速,而且相当冷静,那么它的实际运行表现如何呢?这款硬盘的运行噪声仅有1.8dB~2.8dB,只在开始读写操作时会有类似滚珠碰撞的微小响声,而大部分时间基本保持静音运行,虽偶尔会有类似启动时的声音,但音量很低,只有在深夜等极安静的环境中,距离很近时才能听到。
如果是进行持续读写的话,前期会有类似声音,之后随着256MB大容量缓存逐渐起效,其偶发噪声也会逐渐减少。
其运行功率为7.9W,在室温26℃时,单硬盘持续高负载运行时的最高温度维持在43℃。
多硬盘系统中,只要保持正常的通风散热,工作温度基本不会超过50℃。
这款产品采用标准的S A T A6Gbps接口,尽管容量已经超过了很多主板、NAS、服务器的标称最大支持容量,但实际上大都可以很好地识别和运行,因此升级时对周边的需求并不高。
酷狼硬盘采用AgileArray固件,针对NAS服务器进行了优化,可为客户提供多种优势,特别是在多硬盘R A I D方面,支持优RAID性能、双面平衡、旋转振动(RV)传感器、高级电源管理和错误恢复控制。
因此其RAID性能相当出色,RAID 0读写速度可达到350MB//s~470MB/s。

另外这些硬盘享有 5 年有限保修服务。
IcePack 安装架拥有自己独特的框架 2.5 英寸硬盘封装在适合底板的 3.5 英寸安装架内,内置的散热器可确保这款强大精巧的硬盘在安装到高性能台式机箱后能以超低温运行。
NoTouch 斜坡加载技术记录磁头永远不与磁盘介质相接触,最大限度降低对记录头、介质的磨损,确保硬盘在运输过程中受到更好的保护。
预先磨损平衡(PWL)确保极有可能在磁盘同一个物理位置上执行读写操作的应用程序稳定地运行。
旋转加速前馈(RAFF)当硬盘应用于易振型多硬盘系统中时,可对硬盘运行和性能进行优化。
WD Red 通俗称为红盘,一般作为企业级硬盘使用,价格也相对贵。
特点如下:双端口,全双工连接能力。
消除单点故障,具有更高的可靠性、性能和数据可用性,专为领先关键任务企业拓扑系统而设计。
NoTouch 斜坡加载技术记录磁头永远不与磁盘介质相接触,最大限度降低对记录头、介质的磨损,确保硬盘在运输过程中受到更好的保护。
双级驱动技术磁头定位系统有两个驱动器,能够提高在数据轨道上定位的精度。
主驱动器采用常规电磁驱动器原理,可对磁头进行粗略位移调整。
辅助驱动器利用压电运动对磁头定位进行微调,以提高定位精度。
RAFF技术增强的RAFF 技术融入了精密的电子元件,能够监控硬盘并对线性和旋转振动进行实时纠正。
因此在高振动环境中性能比前几代硬盘有了显著提升。
RAID 专门的限时错误恢复技术(TLER)防止硬盘因硬盘错误恢复时间过长而出现故障,这类故障常见于台式机硬盘。
