Product overview of the Western Digital WD30EZRZ

The WD30EZRZ is an internal hard disk drive (HDD) designed by Western Digital for use in desktop computers. It is part of the Western Digital Blue series, which is known for its reliability, performance, and affordability. In this article, we will provide a detailed explanation of the features and specifications of the WD30EZRZ hard disk drive.


The WD30EZRZ HDD has a storage capacity of 3TB, which provides ample storage space for personal and professional use. This capacity is ideal for use in desktop computers that require high-capacity storage solutions for multimedia content, games, and other applications. With 3TB of storage, users can store large files such as photos, videos, and music without worrying about running out of space.

Rotational Speed

The WD30EZRZ hard disk drive has a rotational speed of 5,400 revolutions per minute (RPM). This is a relatively slow rotational speed, but it is suitable for use in desktop computers, as they are primarily used for storing and accessing data, rather than for high-speed performance. The slower rotational speed also reduces heat and noise, which is important for use in home or small office environments.

Buffer Size

The WD30EZRZ HDD has a 64MB buffer size, which is larger than the buffer size of many other hard disk drives. This large buffer size is important for improving the overall performance of the HDD, as it allows for more data to be stored in the buffer for quick retrieval. This feature is particularly useful for desktop computers that require quick access to large amounts of data.

SATA Interface

The WD30EZRZ hard disk drive uses the Serial ATA (SATA) interface, which provides fast data transfer rates of up to 6Gbps. This interface is commonly used in modern computers and provides a reliable and efficient method for connecting storage devices to the motherboard. The SATA interface also ensures that the HDD is compatible with a wide range of desktop computers and devices.

Form Factor

The WD30EZRZ HDD has a 3.5-inch form factor, which is the standard size for desktop hard disk drives. This size allows the HDD to fit securely into most desktop computers. Additionally, the hard disk drive has a low profile design, which reduces the space required to install it into a desktop computer. This feature is particularly useful for small desktop computers that have limited space for storage devices.


The WD30EZRZ HDD is designed for reliability and durability. It uses advanced technologies such as NoTouch Ramp Load technology, which ensures that the recording head never touches the disk surface, reducing wear and tear on the HDD. Additionally, the HDD has a mean time between failure (MTBF) of 1 million hours, which means that it is expected to last for a long time with normal use.


The WD30EZRZ hard disk drive is compatible with a wide range of operating systems, including Windows, Mac OS, and Linux. It also works with most modern desktop computers and can be easily installed using standard mounting screws. The HDD is also compatible with most SATA controllers, ensuring that it can be connected to a wide range of devices.

Energy Efficiency

The WD30EZRZ HDD is designed to be energy-efficient, which is important for reducing power consumption and heat generation. It uses advanced technologies such as IntelliSeek, which calculates the optimum seek speeds to reduce power consumption, noise, and vibration. Additionally, the HDD is compliant with the RoHS directive, which restricts the use of hazardous materials in electronic products, making it an eco-friendly option for storage solutions.

Noise and Vibration

The WD30EZRZ HDD is designed to reduce noise and vibration, which is important for maintaining a quiet and stable computing environment
