Product Overview of the Seagate ST32000542AS

ST32000542AS is a Seagate Barracuda internal hard drive that is designed to provide high storage capacity, reliable performance, and efficient data transfer rates. In this article, we will discuss the technical specifications, features, and benefits of the ST32000542AS hard drive.

The ST32000542AS hard drive has a storage capacity of 2TB, which is equivalent to 2000GB. It operates at a speed of 5.9K RPM (rotations per minute) and has a 32MB buffer size. The hard drive uses the Serial ATA (SATA) interface to connect to the motherboard and transfer data.

In the ever-evolving landscape of data storage solutions, the Seagate ST32000542AS Barracuda 2TB Hard Disk Drive (HDD) has emerged as a noteworthy contender. This detailed review will explore the various facets of this storage device, providing insights into its specifications, performance, and overall suitability for different applications.

Key SpecificationsStorage Capacity

At the heart of the Seagate ST32000542AS lies its impressive storage capacity of 2 terabytes. This immense space makes it well-suited for users with extensive data storage needs, whether for personal use or professional applications.

Rotational Speed

The rotational speed, measured in Revolutions Per Minute (RPM), is a critical factor influencing the performance of a hard drive. The ST32000542AS operates at 5900 RPM, striking a balance between speed and power efficiency.

The spindle speed of 5900 RPM ensures that the hard drive's platters rotate at a sufficient speed, contributing to efficient data access and transfer. This balance is particularly valuable for users who prioritize both performance and energy efficiency.

Serial Advanced Technology Attachment (SATA)

The SATA interface is the bridge that connects the hard drive to the rest of the computer system. The ST32000542AS utilizes SATA, ensuring a reliable and high-speed data transfer process. This SATA connection is essential for seamless communication between the hard drive and other components of the system.

Buffer Size: 32MB

The inclusion of a 32MB buffer, also known as a cache, enhances the hard drive's ability to handle data more efficiently. This temporary storage area contributes to faster read and write operations, ultimately optimizing overall system performance.

3.5-inch Large Form Factor (LFF)

The physical size of the hard drive, known as the form factor, plays a crucial role in determining its compatibility with different systems. The ST32000542AS adopts the 3.5-inch Large Form Factor (LFF), making it suitable for desktop configurations where space is not as constrained as in laptops.

The form factor of a hard drive refers to its physical size and shape. The ST32000542AS hard drive has a form factor of 3.5 inches, which is the standard size for desktop internal hard drives. It measures 146.99mm (length) x 101.6mm (width) x 26.11mm (height) and weighs approximately 610g.

Performance Metrics

The ST32000542AS hard drive is designed to deliver high performance and reliable operation. It has a spindle speed of 5.9K RPM, which ensures fast data access and transfer rates. The hard drive also has a 32MB cache, which stores frequently accessed data and improves overall system performance.

The SATA interface used by the ST32000542AS hard drive enables high-speed data transfer rates. It supports SATA II, which has a maximum data transfer rate of 3Gb/s (gigabits per second). This allows the hard drive to quickly transfer large files, such as videos, photos, and music.

Spindle Speed

The 5900 RPM spindle speed of the ST32000542AS strikes a balance between speed and power efficiency. This ensures that the hard drive can deliver a responsive performance without compromising on energy consumption.

Optimizing Latency

Latency measures the time it takes for the hard drive to locate and access data. The ST32000542AS boasts an average latency of 5.1 milliseconds, contributing to quick data retrieval and overall system responsiveness.

Seek Times: Swift and Efficient

The random read-and-write seek times of 16.0 milliseconds indicate the speed at which the hard drive can locate and retrieve specific pieces of data. These swift seek times contribute to the efficient handling of both read and write operations.

The seek times for both random read and random write operations are crucial performance indicators. With efficient seek times of 16.0 milliseconds, the ST32000542AS excels in handling both sequential and non-sequential data access, catering to a variety of computing needs.

Average Latency

Latency measures the time it takes for the hard drive to locate and access data. The ST32000542AS boasts an average latency, enhancing its responsiveness and ensuring that users can access their data with minimal delay.


The ST32000542AS hard drive is designed to be highly reliable and durable. It uses advanced technologies, such as Seagate SmartAlign and Seagate OptiCache, to ensure optimal performance and reliability.

The SmartAlign technology allows the hard drive to seamlessly transition to the new 4K sector size, which is more efficient than the previous 512-byte sector size. This ensures that the hard drive remains compatible with modern operating systems and applications.

The OptiCache technology improves the hard drive's performance by optimizing the cache algorithms and data placement. This ensures that frequently accessed data is stored in the cache, which reduces the time required to access the data and improves overall system performance.

CompatibilitySeamless SATA Integration

With the SATA interface, the ST32000542AS seamlessly integrates into a variety of computing systems. The 7-pin configuration ensures compatibility with a broad range of motherboards, making it a versatile choice for users with different system configurations.

LFF for Desktop

The 3.5-inch Large Form Factor (LFF) makes the ST32000542AS well-suited for desktop configurations. Its size allows for easy installation in standard desktop cases, providing users with a straightforward and compatible storage solution.
