Product Overview of the Toshiba MD08ADA400E 4TB Hard Disk Drive

Toshiba MD08ADA400E is a 4TB SATA hard drive that operates at 6 gigabits per second (GBPS) and a rotational speed of 7,200 revolutions per minute (RPM). This hard drive is designed for use in desktop computers, workstations, and other systems that require high-capacity storage. The Toshiba MD08ADA400E 4 Terabytes (TB) Serial Advanced Technology Attachment (SATA) 6 Gigabytes Per Second (GBPS) 7200 Revolutions Per Minute (RPM) 256 Megabytes (MB) Cache 512E Hard Disk Drive stands out as a robust and high-capacity option.

Storage Capacity of 4 Terabytes (TB)

At the core of the Toshiba MD08ADA400E is its impressive storage capacity of 4 terabytes. This means that the drive can hold an enormous amount of data, making it suitable for a wide range of applications, from personal use to professional and enterprise-level storage needs. For users dealing with large files, such as high-definition videos, extensive databases, or resource-intensive applications, this substantial storage space becomes a key selling point.

SATA Interface

The SATA interface is a critical factor in determining the data transfer speed between the hard disk drive and the computer it's connected to. The Toshiba MD08ADA400E features a SATA interface with a speed of 6 gigabytes per second (GBPS). This high-speed interface ensures swift and efficient data transfer, reducing latency and improving overall system performance. Whether you're transferring large files or running applications with high I/O demands, the SATA 6GBPS interface contributes to a smooth user experience.

Data Transfer Speed

The Toshiba MD08ADA400E hard drive operates at a speed of 6 GBPS, making it capable of transferring data quickly and efficiently. This high data transfer rate ensures that data can be read and written to the hard drive quickly, which is important for tasks such as accessing large files or transferring data between different systems.

Rotational Speed

The rotational speed of a hard drive is measured in revolutions per minute (RPM). The Toshiba MD08ADA400E hard drive has a rotational speed of 7,200 RPM, which is a relatively high speed for a hard drive. This high rotational speed allows data to be accessed quickly and efficiently, which is important for tasks that require high-speed data access, such as gaming or video editing. The 7200 RPM speed is particularly advantageous for activities like video editing, gaming, and other data-intensive processes. It ensures that the HDD can quickly locate and retrieve data, contributing to a smoother user experience. For professionals who rely on efficient data handling, the 7200 RPM speed of the MD08ADA400E becomes a valuable asset.

Cache Size 256 Megabytes (MB)

The cache, or buffer, of a hard disk drive, serves as a temporary storage space for frequently accessed data. In the case of the Toshiba MD08ADA400E, it boasts a substantial 256 megabytes (MB) of cache. A larger cache size can contribute to improved read and write speeds, particularly when dealing with repetitive tasks or accessing frequently used files. This feature is advantageous for applications that involve iterative processes, as the drive can quickly retrieve data from the cache, reducing the time it takes to access information.

512E Technology

The 512E (512 emulation) technology is a crucial aspect of the Toshiba MD08ADA400E. This technology refers to the drive's ability to emulate 512-byte sectors while using 4K physical sectors. In simpler terms, it ensures compatibility with older systems and applications that might not be optimized for the newer 4K sector size standard. This backward compatibility makes the Toshiba MD08ADA400E a versatile choice, as it can seamlessly integrate into various computing environments without sacrificing performance. The adoption of Advanced Format Technology brings several advantages, including increased storage capacity efficiency and improved error correction capabilities. By aligning more closely with modern storage demands, the 512E technology in the MD08ADA400E contributes to better reliability and enhanced performance.


The Toshiba MD08ADA400E hard drive is designed for reliability and durability. It uses advanced technologies to protect data, such as shock sensors that detect when the hard drive is dropped or bumped and temporarily stop the drive to protect data. The hard drive also has a mean time between failures (MTBF) of 1.2 million hours, which is a measure of the expected lifespan of the drive. This high MTBF ensures that the hard drive will provide reliable performance over its lifespan.

Power Consumption

The Toshiba MD08ADA400E hard drive has a low power consumption, making it an ideal choice for use in systems that require energy-efficient components. It has an average power consumption of 6.4 watts when in use and 5.2 watts when idle, which is lower than many other hard drives on the market. This low power consumption also helps to reduce the overall energy usage of the system, which is important for both environmental and cost reasons.

Noise Level

The Toshiba MD08ADA400E hard drive operates at a relatively low noise level, which is important for systems that require quiet operation. It has an idle noise level of 25 decibels (dB) and a seek noise level of 26 dB, which is quieter than many other hard drives on the market. This makes it an ideal choice for use in home or office environments where quiet operation is important.

Applications of 256MB Cache 512e HDD

Data Centers

In the realm of enterprise storage, the Toshiba MD08ADA400E finds its place in data centers where scalability, speed, and data integrity are paramount. With its 4TB capacity, 7200 RPM rotational speed, and advanced technologies like NCQ and 512E, this hard drive caters to the rigorous demands of data-intensive applications, server environments, and virtualization setups.
