Hybrid hard drives, also known as hybrid storage drives or SSHD (Solid State Hybrid Drive), are a combination of traditional hard disk drives (HDD) and solid-state drives (SSD). They have a portion of the storage dedicated to an SSD, typically used for the operating system and frequently accessed files, while the larger capacity is provided by an HDD.
A hybrid drive works by using a caching mechanism that temporarily stores frequently accessed data in the SSD's cache, improving read and write speeds. This improves performance compared to a pure HDD because the system can access the most frequently needed data more quickly without having to wait for the spinning platters of the HDD.
Here's a simple demonstration of how it might work[^4]:
```python
# Assume a hybrid drive is represented as an object
hybrid_drive = HybridDrive()
# Accessing frequently used files
file = hybrid_drive.cache.get('important_file.txt')
# Faster access due to SSD cache
# Writing a large file
hybrid_drive.write('large_data.zip') # Stored on HDD for long-term storage
```
