Technical details
1. Capacity:
- Storage capacity: 200 GB
- The capacity provides sufficient storage for most desktop applications and can be used for various applications such as data storage, backup or as a system drive.
2. Interface:
- SATA (Serial ATA): The HDS722020ALA330 uses the SATA interface, which is one of the most commonly used interfaces for hard drives in PCs and laptops. SATA offers advantages such as simpler cabling and higher data transfer rates compared to older PATA interfaces.
3. Form factor:
- 3.5 inch: The form factor corresponds to the standard for desktop computer hard drives. This form factor is suitable for most desktop PCs and some servers.
4. Speed:
- 7,200 RPM (Revolutions Per Minute): The speed is typical for hard drives in desktop computers and offers a balanced mix of performance and energy efficiency.
5. Cache:
- 8MB Cache: Cache memory improves access times by temporarily storing frequently used data. This helps improve the overall performance of the hard drive.
6. Throughput:
- Data transfer rate: The SATA interface in combination with the 7,200 RPM speed enables transfer rates of up to 300 MB/s, depending on the specific version of SATA (SATA I, II or III). In general, the HDS722020ALA330 is compatible with SATA II, which theoretically enables transfer rates of up to 300 MB/s.
7. MTBF (Mean Time Between Failures):
- Reliability: MTBF values ​​are typically several hundred thousand hours, making the hard drive reliable for use in desktop computers and more demanding applications.
8. Search times:
- Access time: The average access time is typically between 8 and 10 ms, which is fine for a hard drive of this type and generation.
Features
1. SATA-Interface:
- Advantages: Offers simple cabling, higher data transfer rates compared to older IDE interfaces, and is compatible with a wide range of computers and motherboards.
2. Bug correction:
- ECC (Error Correction Code): Protects against data errors and improves data integrity by detecting and correcting errors.
3. Smart Monitoring:
- SMART (Self-Monitoring, Analysis, and Reporting Technology): Allows monitoring of the health of the hard drive and can warn of possible failures by monitoring various operating parameters.
4. Acoustic performance characteristics:
- Noise Level: The hard drive operates in a range optimized for desktop applications. The noise level is typically in the range of 30-40 dB(A), which is typical for desktop hard drives.
5. Energy efficiency:
- Power Consumption: The hard drive is optimized for low power consumption, which contributes to energy efficiency and less heat generation. It consumes less energy when idle than when under full load.
Scope
1. Desktop-Computer:
- General Use: The Hitachi HDS722020ALA330 is ideal for use in desktop computers to store operating systems, applications and data. The combination of capacity, performance and cost makes it a good choice for typical desktop environments.
