MG07ACAxxx 系列

The New Heavyweight Champion in the Capacity Arena.

MG07ACA 企业级容量型 SATA 硬盘采用全球首个 9 磁盘氦气密封设计,提供高达 14TB 的传统磁性记录 (CMR) 容量和 7,200 rpm 高性能。  得益于 3.5 英寸的业界标准尺寸,可方便地集成至云级别存储基础设施、关键业务型服务器和存储系统,以及文件和对象存储解决方案。

MG07ACA 系列采用东芝精密激光焊接技术,将氦气永久性密封在 9 磁盘机械装置内。  氦气密封设计可降低气动阻力,从而降低运行功耗,帮助云级别和软件定义的数据中心等基础设施实现 TCO 目标。

采用经过验证的 CMR/PRM 记录技术,可实现高达 14TB 和 12TB 型号容量,提供最佳兼容性和数据可靠性。  MG07ACA 型号配备 SATA 6.0 Gb/秒接口,可方便地集成至标准 3.5 英寸 SATA 驱动器托架,从而减少云级别存储基础设施、关键业务型服务器和存储系统的占用空间并减轻运营负担。

  • World's First Source : Toshiba Electronic Devices & Storage Corporation, as of December 8,2017.
  • Definition of capacity: A terabyte (TB) is 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1TB = 240 = 1,099,511,627,776 bytes and therefore shows less storage capacity.  Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system and/or pre-installed software applications, or media content.  Actual formatted capacity may vary.
  • A mebibyte (MiB) means 220, or 1,048,576 bytes.
  • MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation.  Actual operating life of the product may be different from the MTTF.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • SIE: Sanitize Instant Erase. SIE is a function to invalidate the data recorded on the magnetic disks at a blink.
  • "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size.
  • PWC (Persistent Write Cache) with PLP (Power Loss Protection) :  PWC with PLP is a function to handle the write data that the drive reports "Normal completion" to the host but not being stored to hard disk media yet. The write data may be written to the commanded LBA on the hard disk media. The un-written data to hard disk media is stored to Flash memory using back up power by PLP when the power supply to the drive suddenly is shut down. And, after PLP operation, it may be required more time to start up the drive than in case of normal shutdown. 1) PLP does not secure data in the mode of all the power shutdowns. When power supplies other than recommended procedure are intercepted, data might be lost. 2) In the power shutdown before it reports on the Write completion, data not anticipated might be lost.
  • PLP (Power Loss Protection): PLP supports to record data in buffer memory to hard disk media utilizing back electromotive force along with media rotation inertia in case of sudden supply shut down.
  • Workload is a measure of the data throughput of the year, and it is defined as the amount of data written, read or verified by commands from the host system.
