Product Overview of the Seagate 450GB Hard Drive

The Seagate ST3450857SS Cheetah is a formidable internal hard disk drive that has garnered attention for its impressive specifications and performance capabilities. In this comprehensive exploration, we will delve into the intricacies of this storage solution, breaking down its key features, technological aspects, and the practical implications of its specifications. From its storage capacity and speed to its innovative Serial-Attached SCSI (SAS) technology, we aim to provide a detailed understanding of the Seagate ST3450857SS Cheetah.

Optimized Data Transfer with 6 Gigabits Per Second (GBPS)

The 6 gigabits per second (GBPS) data transfer speed of the Seagate Cheetah ensures optimal communication between the hard drive and the host system. This high-speed interface minimizes data transfer bottlenecks, allowing for efficient data flow and improved overall system performance. Whether it's transferring large files or handling data-intensive applications, the Cheetah's impressive data transfer rate enhances productivity and user experience.

Storage Capacity 450 Gigabytes (GB)

At the heart of the Seagate ST3450857SS Cheetah is its generous storage capacity of 450 gigabytes. This is a crucial metric for users seeking substantial space to store their data, applications, and multimedia files. To put it in perspective, a drive of this capacity can accommodate a vast collection of high-definition videos, thousands of high-resolution photos, and a multitude of software applications.

Rotational Speed 15000 Revolutions Per Minute (RPM)

The Cheetah's standout feature is its rapid rotational speed of 15000 RPM. This high-speed rotation plays a pivotal role in enhancing data access and transfer rates, resulting in quicker load times for applications and reduced latency. This is especially beneficial for users engaged in data-intensive tasks such as video editing, gaming, or running resource-demanding applications.

Interface Serial-Attached SCSI (SAS)

The Seagate ST3450857SS Cheetah employs Serial-Attached SCSI (SAS) as its interface technology. SAS represents a significant evolution from its predecessor, Parallel SCSI, offering improved data transfer rates, scalability, and reliability. SAS facilitates the connection of multiple devices in a daisy-chain fashion, optimizing the efficiency of data transmission between the hard disk drive and the host system.

Data Transfer Speed 6 Gigabits Per Second (GBPS)

With a data transfer speed of 6 gigabits per second (GBPS), the Seagate Cheetah ensures swift and efficient communication between the hard drive and the host system. This high data transfer rate is instrumental in reducing bottlenecks, enhancing overall system performance, and delivering a seamless user experience. It is particularly advantageous for professionals working with large files or engaging in real-time data processing.

Cache Size 16MB Buffer

The Cheetah is equipped with a substantial 16 megabyte (MB) buffer, also known as cache size. The buffer serves as a temporary storage space for frequently accessed data, allowing for quicker retrieval and improved overall system responsiveness. A larger cache size is especially beneficial in scenarios where repetitive tasks or applications are involved, contributing to a smoother user experience.

Enhanced Performance with 15000 RPM

The standout feature of the Seagate Cheetah is its impressive rotational speed of 15000 RPM. This is a significant leap from traditional hard drives operating at lower RPMs, contributing to faster data access and reduced latency. The enhanced performance is particularly valuable for tasks that demand quick read and write operations, such as gaming, video editing, and multitasking with resource-intensive applications.

Efficient Data Handling with 16MB Buffer

The 16 megabyte (MB) buffer in the Seagate ST3450857SS Cheetah plays a crucial role in optimizing data handling. As a temporary storage space for frequently accessed data, the buffer minimizes the need for repeated retrieval from the main storage, resulting in quicker response times. This is particularly beneficial in scenarios where repetitive tasks or applications are involved, contributing to a more efficient and responsive computing experience.

Professional Workloads Ideal for Content Creators and Video Editors

For professionals engaged in content creation, video editing, and other data-intensive tasks, the Seagate ST3450857SS Cheetah emerges as a reliable choice. Its combination of high storage capacity, rapid rotational speed, and efficient data transfer rates ensures that large files are handled seamlessly. Video editing, in particular, benefits from the Cheetah's ability to quickly access and transfer high-definition video files, reducing the time required for rendering and enhancing overall workflow efficiency.

Gaming Performance Reduced Load Times and Enhanced Gaming Experience

Gamers, too, stand to gain from the Seagate Cheetah's impressive specifications. The 15000 RPM rotational speed significantly reduces load times for games, contributing to a smoother gaming experience. The high data transfer rate ensures that game files are quickly accessed, providing a responsive and lag-free environment for gamers. The Cheetah's reliability and robust design make it a suitable choice for gaming enthusiasts seeking top-tier performance from their storage solution.

Buffer & Form Factor

The ST3450857SS comes with a 16MB buffer, which is also known as the cache. The buffer is a small amount of fast memory located on the hard drive that acts as a temporary storage area for data. The buffer allows the hard drive to perform read and write operations more efficiently by temporarily storing frequently accessed data. The buffer also helps to reduce the number of seek operations required to access data on the disk, leading to improved performance. The ST3450857SS is designed to be used as an internal hard drive and has a form factor of 3.5 inches. The 3.5-inch form factor is the most common size for desktop and server hard drives. The drive's size makes it compatible with a wide range of storage systems and chassis.


The ST3450857SS is designed to be highly reliable and has a mean time between failure (MTBF) of 1.6 million hours. This means that the drive is expected to run for 1.6 million hours before it fails. The drive also comes with Seagate's RAID Rebuild technology, which ensures that data is rebuilt quickly and accurately in the event of a drive failure.
