The MG04ACA Enterprise Capacity HDD models provide capacities up to 6 TB and 7,200 rpm performance, in a robust design engineered for nearline business-critical workloads.
The MG04ACA series utilizes industry-standard 3.5-inch 26.1 mm height form factor and Advanced Format sector technologies for optimum capacity and data reliability. 512e 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 MG04ACA models help save rack space and reduce the footprint and operational burden of business critical servers and storage systems.
512e or 4Kn Advanced Format sector technology models are available. 4Kn models (MG04ACAxxxA) offer optimum performance and compatibility with the 4K applications and operating environments. 512e models (MG04ACAxxxE) provide support for legacy applications and operating environments that require 512 B 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.
  • Toshiba Storage & Electronic Devices Solutions Company defines "RoHS-Compatible" products as products that either (i) contain no more than a maximum concentration value of 0.1% by weight in Homogeneous Materials for lead, mercury, hexavalent chromium, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) and of 0.01% by weight in Homogeneous Materials for cadmium; or (ii) fall within any of the application exemptions set forth in the Annex to the RoHS Directive (Directive 2011/65/EC of the European Parliament and of the Council of 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment). "Homogeneous Material" means a material of uniform composition that cannot be mechanically disjointed (meaning separated, in principle, by mechanical actions such as unscrewing, cutting, crushing, grinding and/or abrasive processes) into different materials. Examples of "Homogeneous Materials" would be individual types of plastics, ceramics, glass, metals, alloys, paper, board, resins and coatings.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • 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.
  • "2.5-inch" and "3.5-inch" mean the form factor of HDDs or SSDs. 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.
