Similar read and write speeds could certainly be achieved with the Hitachi HDS722020ALA330 SCSI Disk Device under Linux and MacOS. Of course, the correct hard drive driver should be installed and the correct interface for the Hitachi HDS722020ALA330 SCSI Disk Device should be used.
The Hitachi HDS722020ALA330 is an internal hard drive from Hitachi's Deskstar series designed for desktop computing applications. This hard drive offers a combination of high capacity, solid performance and reliability, and it is especially suitable for desktop computers. Here are the comprehensive technical details, features and application areas of this hard drive.
Technical Details
1. Capacity:
- 200 Gigabytes (GB). The 200 GB capacity provides ample storage for operating systems, applications as well as personal data such as documents, music and videos. This capacity is suitable for everyday tasks and smaller storage spaces.
2. Form Factor:
- 3.5 inches. The 3.5 inch form factor is the standard for desktop hard drives and will fit into most desktop cases designed for 3.5 inch drives.
3. Interface:
- SATA I (SATA 1.5 Gb/s). The SATA I interface allows a maximum data transfer rate of up to 1.5 Gb/s (150 MB/s). SATA I is the first generation of the Serial ATA standard and offers lower bandwidth compared to later generations such as SATA II and SATA III.
4. Rotational Speed:
- 7,200 rpm). A rotational speed of 7,200 rpm is standard for desktop hard drives and offers a good ratio of performance to power consumption. It ensures relatively fast access times and data transfer rates.
5. Cache Memory:
- 8 megabytes (MB). Cache memory is used to temporarily store frequently accessed data, improving performance by speeding up access to that data.
6. Error Correction Technology:
- Error Recovery Control (ERC). This technology helps detect and correct data errors to increase the reliability of the hard drive.
7. Operating and environmental conditions:
- Operating temperature: Typically 0 to 60 °C.
- Storage temperature: Typically -40 to 70 °C. These temperatures ensure that the hard drive functions reliably under various conditions.
8. Power consumption:
- Operating consumption: Approximately 6 to 8 watts.
- Idle: Approximately 5 watts. These values ​​​​show the energy consumption of the hard drive during operation and when idle.
9. MTBF (Mean Time Between Failures):
- Typically over 750,000 hours. This indicates high reliability and a long lifespan of the hard drive.
Features
1. High capacity for desktop use:
- With 200 GB, the hard drive offers sufficient storage space for the operating system, applications, and a reasonable amount of personal data.
2. Fast data transfer:
- The SATA I interface enables a maximum transfer rate of up to 1.5 Gb/s, which is sufficient for most desktop applications.
3. Good performance:
- The 7,200 RPM rotation speed ensures balanced performance that enables fast access times and data transfer rates without unnecessarily increasing energy consumption.
4. Cache memory:
- The 8 MB cache memory improves the performance of the hard drive by caching frequently used data and enabling faster access to it.
5. Error correction technologies:
- ERC technology improves data integrity and reduces the risk of data errors, increasing the reliability of the hard drive.
6. Reliability:
- High MTBF values ​​and advanced error correction technologies ensure a long service life and reliable performance.
Application Area
1. Desktop Computing:
- The HDS722020ALA330 is ideal for use in desktop PCs, where it can be used as the main drive for the operating system and applications.
2. Media File Storage:
- With 200GB of storage, the hard drive is well suited for storing photos, music and videos.
3. Backup and Archiving Solutions:
- The hard drive can also be used for backup and archiving solutions to store important data.
4. System Upgrades:
- It is suitable for system upgrades to expand the storage space of a desktop system and provide more capacity for new applications and data.
5. Affordable Storage Solutions:
- The hard drive is a cost-effective solution that offers good performance and capacity for users who do not have extremely high demands on speed and performance.
6. Gaming:
- The hard drive can also be used for storing and running games that require storing large amounts of data.
Summary
The Hitachi HDS722020ALA330 is a 200GB 3.5-inch hard drive that features a SATA I interface and a rotation speed of 7,200 RPM. It offers a balanced mix of capacity, performance and reliability and is particularly well suited for desktop computing, media file storage, backup and archiving solutions, and system upgrades. With an 8MB cache and advanced error correction technology, the hard drive offers good performance while maintaining high reliability. It is a cost-effective solution for many applications that require solid performance and sufficient storage capacity.
