The Western Digital WD6400AAKS-00A7B0 is a 640 GB hard drive that belongs to the WD Caviar Blue series. This series is known for its reliability and performance in the field of desktop hard drives. The WD6400AAKS-00A7B0 offers a good balance between capacity and performance and is suitable for both everyday applications and more demanding tasks.
Technical details and specifications
1. Product type:
- The WD6400AAKS-00A7B0 is a 3.5-inch ATA (PATA) hard drive. This type of hard drive uses the Parallel ATA (PATA) interface, which is suitable for older desktop computers and some older laptops.
2. Storage capacity:
- The hard drive offers a storage capacity of 640 GB. This provides enough space for a large amount of data, including operating systems, applications, documents, images, videos and other files.
3. Form factor:
- The hard drive uses the 3.5-inch form factor used in most desktop computers and external hard drive enclosures. This form factor is designed for larger desktop cases and can accommodate larger, higher capacity hard drives.
4. Interface:
- The WD6400AAKS-00A7B0 uses the SATA I (SATA 1.5 Gb/s) interface. SATA I offers a maximum theoretical bandwidth of up to 1.5 Gb/s (150 MB/s). This interface is backwards compatible and can be used in older systems that support SATA I.
5. Speed:
- The hard drive has a speed of 7,200 RPM (revolutions per minute). This speed is standard for desktop hard drives and provides good performance for everyday applications and data access.
6. Cache memory:
- The WD6400AAKS-00A7B0 is equipped with a 16 MB cache. The cache memory helps to process frequently used data faster by temporarily storing this data and speeding up access to it.
7. Seek times:
- The average access time of the hard drive is about 8.9 ms. This access time indicates how quickly the hard drive can access data. A lower access time means faster response times when reading and writing data.
8. Data transfer rates:
- The hard drive offers a maximum transfer rate of up to 150 MB/s, which is limited by the SATA I interface. The actual transfer rate may vary depending on the system configuration and data types.
9. Construction and design:
- The WD6400AAKS-00A7B0 is housed in a robust 3.5-inch housing. The housing protects the internal components of the hard drive and ensures reliable performance. It is also designed to efficiently dissipate heat to prevent overheating.
10. Operating Temperature:
- The hard drive is designed to operate in a temperature range of 0 to 60°C. This operating temperature ensures reliable performance under normal operating conditions.
11. Power Consumption:
- The WD6400AAKS-00A7B0 has a typical power consumption of about 8.5 W when operating and about 5.5 W when idle. This shows that the hard drive is relatively energy efficient, which is especially important for operation in desktop systems.
12. Lifespan and Reliability:
- The hard drive offers a MTBF (Mean Time Between Failures) of about 600,000 hours. This gives a rough idea of ​​how long the hard drive should operate reliably under normal operating conditions.
Features
1. High Storage Capacity:
- The WD6400AAKS-00A7B0 offers a generous amount of 640GB of storage space, which is sufficient for most desktop applications and data needs. This is ideal for users who need to store large amounts of data.
2. Good performance:
- With a rotational speed of 7,200 RPM, the hard drive offers solid performance for accessing and processing data. The combination of this rotational speed and a 16MB cache ensures fast access times and data transfer rates.
3. Energy efficiency:
- The relatively low energy consumption values ​​make the WD6400AAKS-00A7B0 an energy-efficient choice for desktop computers, contributing to lower electricity costs and a longer hardware life.
4. Reliability:
- The high MTBF and robust construction ensure reliable performance designed for long-term use in desktop computers.
5. Compatibility:
- The use of the SATA I interface ensures compatibility with many older desktop systems that have SATA interfaces. Backward compatibility makes the hard drive a flexible choice for upgrades.
Application Range
1. Desktop Computers:
- The WD6400AAKS-00A7B0 is great for desktop computers where it can be used as the primary hard drive for operating systems, applications and data.
2. Storage Expansion:
- This hard drive can be used as an additional storage expansion to increase the existing storage space of a computer. It can also serve as a secondary hard drive for data storage and backup.
3. System Upgrade:
- For users who want to upgrade from an older hard drive to a larger hard drive, the WD6400AAKS-00A7B0 is a good upgrade solution to get more storage space without compromising performance.
4. Data storage and backup:
- The hard drive is well suited for data storage and backup solutions as it offers sufficient capacity for large amounts of data and provides reliable performance.
5. Home and office applications:
- It is ideal for home and office applications including storing documents, media and software applications. The hard drive offers good performance for general computing tasks.
