企業級 HDD

企業級容量型 HDD

MG07ACAxxx 系列

The New Heavyweight Champion in the Capacity Arena.

MG07ACA 企業級容量型 SATA 硬碟採用世界首創 9 碟片氦氣密封設計,最高提供 14TB 傳統磁記錄 (CMR) 容量及 7,200 rpm 效能。產業標準 3.5 吋外型規格可輕鬆整合至雲端級的儲存基礎架構、業務關鍵型伺服器與儲存裝置,以及檔案與物件儲存解決方案。

MG07ACA 系列採用 Toshiba 精準雷射焊接技術,可於整段硬碟機使用壽命將氦氣密封在 9 磁碟的機構中。氦氣密封技術可減少空氣力學阻力,提供更低的運作電力需求,協助雲端級及軟體定義資料中心基礎架構達成總擁有成本目標。

透過 CMR/PRM 記錄技術提供 14TB 與 12TB 機型的大容量,這些技術提供最佳的相容性與資料可靠性。MG07ACA 機型配備 SATA 6.0 Gbit/s 介面,可輕鬆整合至 3.5 吋 SATA 硬碟機插槽,有助於降低雲端級儲存基礎架構、業務關鍵型伺服器和儲存系統的佔地面積和作業負擔。

  • 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.
