Overview of Seagate ST373307LW

The Seagate ST373307LW, or Cheetah 73.4GB, is a high-performance internal hard disk drive designed for enterprise and server environments. This HDD is part of the Seagate Cheetah series, which is known for its speed, reliability, and durability. Let's break down the essential features that make this HDD a standout choice in the world of data storage.

Capacity: 73.4 Gigabytes (GB)

The Seagate ST373307LW boasts a substantial storage capacity of 73.4GB. This level of storage is particularly well-suited for applications that require ample space for data storage, such as large databases, multimedia content, and high-definition video files. For business and enterprise users, having this significant storage capacity can help ensure that all critical data is stored without the need for constant expansion.

Speed: 10K Revolutions Per Minute (RPM)

One of the defining features of the Seagate Cheetah series, including the ST373307LW, is its high rotational speed. This HDD operates at 10,000 RPM (Revolutions Per Minute). The higher RPM translates to faster data access and improved performance. This level of speed is crucial for applications that require quick data retrieval, such as real-time data processing, high-transaction databases, and online transaction processing (OLTP) systems. With a 10K RPM drive, users can expect reduced latency and enhanced I/O (Input/Output) performance.

Interface: Ultra320 68 PIN SCSI

The Seagate ST373307LW utilizes an Ultra320 68 PIN SCSI interface for connectivity. SCSI (Small Computer System Interface) is a high-performance interface commonly used in enterprise environments. The "Ultra320" designation signifies that the drive supports the Ultra320 SCSI standard, which is known for its fast data transfer rates. The 68 PIN connector is a feature specific to SCSI drives and ensures a secure and reliable connection to the host system.

The SCSI interface offers advantages such as support for multiple devices on a single bus, exceptional data transfer rates, and robust error handling. This makes the Seagate Cheetah HDDs, like the ST373307LW, a preferred choice for servers, workstations, and storage arrays in enterprise settings.

Buffer: 8 Megabytes (MB)

The Seagate ST373307LW is equipped with an 8MB buffer. The buffer, often referred to as the cache, plays a crucial role in enhancing the HDD's performance. It serves as a temporary storage area for frequently accessed data, reducing the time it takes to retrieve data from the physical disk platters. This results in faster data access times and improved overall system responsiveness.

A larger buffer size, such as the 8MB in the ST373307LW, is advantageous for tasks that involve data-intensive operations, such as file transfers, database queries, and multitasking. The buffer acts as a bridge between the slower mechanical components of the HDD and the faster system memory, helping to maintain a smooth and efficient data flow.

Form Factor: 3.5 Inch Low Profile

The Seagate Cheetah ST373307LW is designed in a 3.5-inch low-profile form factor. The "3.5-inch" measurement refers to the physical size of the HDD, making it suitable for standard drive bays found in most computer cases, workstations, and servers. The "low profile" aspect ensures that the drive's height is minimal, making it compatible with systems with space constraints.

The 3.5-inch form factor is a common standard for internal hard drives, and it is well-received for its versatility and ease of installation. This compact size allows users to integrate the Seagate Cheetah ST373307LW into various systems without major modifications.

Reliability and Durability

Enterprise environments demand reliable and durable storage solutions, and the Seagate Cheetah ST373307LW does not disappoint in this regard. Seagate is renowned for its commitment to producing HDDs that can withstand the rigors of continuous operation.

The Cheetah series, in particular, is known for its robust build quality and ability to perform under heavy workloads. These drives are engineered to handle 24/7 operation, making them suitable for servers and enterprise-class storage systems. Seagate's years of experience in HDD manufacturing and their focus on quality assurance ensure that the ST373307LW is a dependable choice for critical data storage needs.

The ST373307LW Seagate Cheetah hard disk is a high-performance internal hard disk designed for enterprise storage applications. The hard disk features a storage capacity of 73.4GB, a spindle speed of 10K RPM, and a SCSI, making it suitable for storing and retrieving large amounts of data quickly.

In this article, we will discuss the features and specifications of the ST373307LW Seagate Cheetah hard disk in detail.

Capacity and Interface

The ST373307LW Seagate Cheetah hard disk has a storage capacity of 73.4GB, which is sufficient for storing large amounts of data, including multimedia, databases, and applications. The hard disk uses the Small Computer System Interface (SCSI) interface, which is a popular interface used in enterprise storage systems.

The SCSI offers a high data transfer rate of up to 320MB/s, which allows the hard disk to transfer data quickly and efficiently. The interface is also compatible with older SCSI interfaces, which means the hard disk can be used with legacy storage systems.

Spindle Speed and Buffer

The ST373307LW Seagate Cheetah hard disk has a spindle speed of 10K RPM, which means it rotates 10,000 times per minute. The high spindle speed makes the hard disk suitable for applications that require high data transfer rates, such as data processing, multimedia, and transaction processing.

The hard disk also features an 8MB buffer, which is used to temporarily store data before it is written to or read from the hard disk. The buffer helps to improve the overall performance of the hard disk by reducing the access time to frequently accessed data.

Physical Specifications

The ST373307LW Seagate Cheetah hard disk has a 3.5-inch form factor, which is the standard size for enterprise hard disks. The hard disk has a height of 1 inch, a width of 4 inches, and a depth of 5.8 inches. The hard disk weighs approximately 1.5 pounds.

The hard disk uses perpendicular magnetic recording (PMR) technology, which allows it to store data more compactly. The PMR technology also helps to increase the storage density of the hard disk, which means it can store more data per unit of space.

Error Correction and Data Integrity

Data integrity is paramount in enterprise environments. The Seagate Cheetah ST373307LW incorporates advanced error correction and data protection mechanisms to ensure that data remains safe and accurate. These mechanisms include features like Error Correction Code (ECC) and various error recovery technologies.

ECC is a crucial component of data integrity. It helps identify and correct errors that may occur during data storage or retrieval, preventing data corruption. The Seagate Cheetah series is known for its robust ECC capabilities, further enhancing the drive's reliability.
