Data Storage Device and Method for Prediction-Based Improved Power-Loss Handling - A simplified explanation of the abstract
This abstract first appeared for US patent application 17839615 titled 'Data Storage Device and Method for Prediction-Based Improved Power-Loss Handling
Simplified Explanation
The abstract describes a data storage device and method that improves power-loss handling by predicting the probability of an ungraceful shutdown and reducing the risk of data loss in response to this prediction.
- The data storage device includes a memory and a controller.
- The controller is programmed to predict the likelihood of an ungraceful shutdown occurring.
- It determines if the probability of an ungraceful shutdown is higher than a predefined threshold.
- If the probability exceeds the threshold, the controller takes measures to minimize the risk of data loss during the shutdown.
- The invention can be implemented in various embodiments and can be used alone or in combination with other embodiments.
Potential Applications
This technology can be applied in various industries and scenarios where data storage devices are used, such as:
- Computer systems and servers
- Data centers
- Cloud storage services
- Embedded systems
- Industrial control systems
Problems Solved
The technology addresses the following problems related to power-loss handling in data storage devices:
- Ungraceful shutdowns can lead to data loss and corruption.
- Sudden power loss can occur due to various reasons, such as power outages or system failures.
- Traditional power-loss handling methods may not effectively mitigate the risk of data loss during ungraceful shutdowns.
Benefits
The use of this technology offers several benefits:
- Improved reliability and data integrity by reducing the risk of data loss during power loss events.
- Enhanced system performance and uptime by minimizing the impact of ungraceful shutdowns.
- Increased user satisfaction and trust in data storage devices.
- Cost savings by avoiding potential data recovery efforts or loss of critical information.
Original Abstract Submitted
A data storage device and method for prediction-based improved power-loss handling. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to predict a probability of an ungraceful shutdown of the data storage device; determine whether the probability is greater than a threshold; and in response to determining that the probability is greater than the threshold, reduce a risk of data loss that would occur in response to the ungraceful shutdown of the data storage device. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
