The ST9500423AS ATA Device is a hard drive from Seagate Technology that stands out for its specific technical details and features. Here is a detailed description including technical details, features and application area:
General Description
The ST9500423AS is a 2.5-inch hard drive from Seagate that connects via an ATA (Advanced Technology Attachment) interface. This hard drive is designed for use in laptops and other compact computers and offers a balance between capacity, performance and energy efficiency. The hard drive is intended as an internal storage solution and is often used in mobile devices such as laptops or portable external hard drive systems.
Technical Details
- Model Name: ST9500423AS
- Capacity: 500 GB - This capacity provides sufficient storage space for operating systems, applications and personal data such as documents, music and videos.
- Form Factor: 2.5 inches – This is the standard form factor for laptop hard drives and also for external hard drive systems.
- Interface: ATA/IDE (Integrated Drive Electronics) – The ST9500423AS uses the ATA interface, also known as IDE. This interface offers a maximum transfer rate of up to 133 MB/s (for PATA).
- Rotational Speed: 5,400 RPM – The hard drive runs at a moderate rotation speed that provides a balance between performance and energy efficiency. 5,400 RPM is commonly found in mobile devices.
- Cache Memory: 8 MB – The cache helps to cache frequently used data to reduce access times and improve overall performance.
- Average Access Time: Around 12-14 ms – This access time describes how long, on average, it takes the hard drive to access a specific data location.
Features
- High Capacity: With 500 GB, the hard drive offers sufficient storage space for a variety of applications and large amounts of data.
- Energy Efficiency: The moderate speed of 5,400 RPM reduces energy consumption, which is especially important for use in laptops where battery life is a critical factor.
- Quiet Operation: The hard drive is designed to operate relatively quietly, which ensures a pleasant user experience, especially in quiet environments.
- Error Correction: The hard drive uses error correction technologies to ensure data integrity and correct data errors.
- Vibration Resistance: The ST9500423AS is equipped with technologies that protect the hard drive against shocks and vibrations, increasing its durability, especially in mobile applications.
Application Area
- Laptops: The ST9500423AS is ideal for use in laptops, where the 2.5-inch form factor and ATA interface are well suited. It offers sufficient storage capacity and is energy efficient.
- Portable Hard Drives: The hard drive can also be used in portable hard drive systems where a 2.5-inch drive is required.
- Desktop PCs: Although the form factor for desktop PCs is smaller than the common 3.5-inch drives, the ST9500423AS can be used in desktop PCs that support 2.5-inch hard drives.
- Backup Solutions: It can be used for simple backup purposes to store and back up data from various devices.
Benefits and Challenges
Benefits
- Capacity: At 500GB, the hard drive offers enough storage space for most everyday applications and data.
- Energy Efficiency: The low power consumption is ideal for mobile devices that rely on long battery life.
- Quiet: The hard drive operates relatively quietly, which reduces noise and creates a quieter work environment.
Challenges
- Performance: The 5400 RPM rotation speed is lower than faster 7200 RPM or 10,000 RPM hard drives, which can result in slower access times and data transfer rates.
- Compatibility: Because the ATA interface is older, there may be difficulties using the hard drive in modern systems that primarily support SATA interfaces. An adapter or equivalent interface is required.
- Capacity: At 500 GB, the capacity is limited compared to modern SSDs or HDDs, which can be multiple terabytes in size. For larger amounts of storage, other options are required.
Conclusion
The ST9500423AS from Seagate is a solid 500GB 2.5-inch hard drive that stands out for its moderate speed and energy efficiency. It is designed for use in laptops and portable hard drive systems and offers reliable performance for everyday storage needs. Although it does not offer the highest performance or capacity compared to newer technologies, it is a suitable choice for users looking for an economical and reliable storage solution.
