Enterprise HDD

Enterprise Capacity HDD

MG05ACA800A / MG05ACA800E

The MG05ACA Enterprise Capacity HDD provides 8TB of capacity and 7,200 rpm performance, in a robust design engineered for nearline business-critical workloads.

The MG05ACA utilizes industry-standard 3.5-inch 26.1 mm height form factor and Advanced Format sector technologies for optimum capacity and data reliability. This models support Toshiba Persistent Write Cache technology which helps enhance performance with handling data in the event of a sudden loss of power. Equipped with SATA 6.0 Gbit/s interface, the Enterprise Capacity MG05ACA models help save rack space and reduce the footprint and operational burden of business critical servers and storage systems.

The MG05ACA improves sustained transfer rate performance by 12% when compared to the prior MG04ACA series. 512e or 4Kn Advanced Format sector technology models are available. 4Kn sector models (MG05ACAxxxA) offer optimum performance and compatibility with the 4Kn-capable applications and operating environments. 512e sector models (MG05ACAxxxE) provide support for legacy applications and operating environments that require 512 byte sector lengths.

  • 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.
