MG04ACA Series
The MG04ACA Enterprise Capacity HDD models provide capacities up to 4 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: One terabyte (TB) = one trillion bytes, but storage capacity actually available may vary depending on operating environment and formatting. 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 1048576 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.
- The HDDs which have any security function may not be available in the countries where the use of such HDDs is prohibited or limited due to export control and local regulations.
- "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size.
- 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.
