Product Overview

In the dynamic landscape of server technology, the choice of storage solutions plays a pivotal role in ensuring optimal performance and reliability. One such powerhouse in the realm of Hard Disk Drives (HDDs) is the Cheetah 450GB Serial-Attached SCSI (SAS) drive. This article delves into the intricacies of this formidable storage device, exploring its key features, benefits, and how it stands out in the competitive market.

The Cheetah 450GB SAS HDD is a cutting-edge storage solution designed for server environments. Let's break down the key specifications that define its capabilitie


450GBThe 450GB capacity signifies the amount of data the drive can store. In server applications, where vast amounts of data are processed and stored, having a high-capacity drive is essential for seamless operations.

SAS Interface

Unleashing Speed and EfficiencyThe Serial-Attached SCSI (SAS) interface is a critical component that defines the data transfer capabilities of the HDD. The SAS interface provides a robust and high-performance connection between the HDD and the server, ensuring rapid data transfer and efficient communication.

Rotational Speed

15000 RPM (Revolutions Per Minute)The rotational speed of the Cheetah 450GB SAS HDD is an impressive 15000 RPM. This high rotational speed significantly enhances data access times, making it ideal for applications that demand quick and responsive storage solutions.

Data Transfer Rate

Gigabits Per Second (3GBPS)The Gigabits Per Second (3GBPS) data transfer rate further accentuates the drive's efficiency. This metric measures how quickly data can be transmitted between the HDD and the server, ensuring that data-intensive tasks are executed with minimal latency.

Buffer Size

16MB (Megabyte)The 16MB buffer size, or cache, is a temporary storage area on the HDD that facilitates smoother data transfer. A larger buffer size allows the drive to handle bursts of data more effectively, contributing to overall system performance.

Form Factor

3.5inch Low ProfileThe 3.5-inch low-profile form factor is a design element that ensures compatibility with various server configurations. The low-profile design is particularly advantageous in environments where space is a premium, allowing for more flexible installation options.

Now that we have a comprehensive understanding of the specifications, let's explore the specific advantages that make the Cheetah 450GB SAS HDD a preferred choice for server applications.

Performance Prowess

The combination of a high rotational speed (15000 RPM) and a robust SAS interface ensures exceptional performance. This makes the Cheetah 450GB SAS HDD particularly well-suited for applications that demand rapid data access and transfer, such as database management and virtualization.

Reliability and Durability

In server environments, reliability is paramount. The Cheetah 450GB SAS HDD is engineered for durability, with components designed to withstand the continuous demands of data-intensive tasks. This reliability factor is crucial for maintaining the stability of critical server operations.

Optimized Data Transfer

With a Gigabits Per Second (3GBPS) data transfer rate, this HDD excels in optimizing the flow of data between the storage device and the server. This becomes especially crucial in scenarios where large datasets need to be processed swiftly, such as in scientific research or financial analysis.

Efficient Caching

The sizable 16MB buffer size enhances the drive's ability to handle data efficiently. This feature becomes particularly beneficial when dealing with applications that involve frequent access to small pieces of data, as the buffer acts as a temporary storage area for quick retrieval.

Space-Efficient Design

The 3.5-inch low-profile form factor of the Cheetah 450GB SAS HDD ensures that it can seamlessly integrate into servers with space constraints. This design flexibility makes it a versatile choice for a variety of server configurations.

Applications and Use Cases

The Cheetah 450GB SAS HDD's impressive specifications and performance make it an ideal choice for a range of server applications. Here are some key scenarios where this HDD shines
