企業級 HDD

企業級容量型 HDD

MG05ACA800A / MG05ACA800E

MG05ACA 企業級容量型硬碟可提供 8 TB 的容量以及 7,200 rpm 的效能,堅固穩當的設計,專為近線業務關鍵型的工作負載所打造。

MG05ACA 採用了產業標準的 3.5 吋、26.1 mm 高的外型規格,並搭載先進格式磁區技術,造就出最佳的容量與資料可靠性。這款型號支援 Toshiba 持續性寫入快取技術,能妥善因應突發斷電的情況,有效提升效能表現。企業級容量型的 MG05ACA 型號配備 SATA 6.0 Gbit/s 介面,可節省機架空間,並降低業務關鍵型伺服器和儲存系統的佔地面積和作業負擔。

相較於先前的 MG04ACA 系列,MG05ACA 的持續傳輸率效能提高了 12%。亦有 512e 或 4Kn 先進格式磁區技術型號。4Kn 磁區型號 (MG05ACAxxxA) 可在具備 4Kn 功能的應用程式和作業環境中,提供最佳效能和相容性。512e 磁區型號 (MG05ACAxxxE) 可支援需要 512B 磁區長度的舊型應用程式和作業環境。

  • Product image may represent a design model.
  • Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes.  A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 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, such as Microsoft Operating System and/or pre-installed software applications, or media content.  Actual formatted capacity may vary.
  • A kibibyte (KiB) means 210, or 1,024 bytes, a mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 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.
  • 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.
  • "2.5-inch" and "3.5-inch" mean the form factor of HDDs or SSDs. They do not indicate drive's physical size.
  • Workload is defined as the amount of data written, read or verified by commands from host system.
