iOS Disk Usage

Measures the amount of data the app reads and writes (in MB) to the device’s disk during a session.

How does it impact user experience

Excessive disk writes can degrade app performance, cause disk write exceptions, and increase wear on device storage. To improve responsiveness and avoid these issues, it’s crucial to minimize disk writes.

Threshold Guidelines

Recommended thresholds are :

• Total Disk Reads (MB) <100 MB in a session
• Total Disk Writes (MB) < 20 MB in a session

How to improve Disk Usage

Following are the recommendations to improve Disk Usage :

• Reduce unnecessary file operations: Avoid excessive file read and write operations to improve app performance and prevent storage wear.
• Use caching: Use caching techniques to store frequently accessed data in memory and minimize the need for disk I/O operations.
• Optimize database queries: Use efficient queries to reduce the number of database reads and writes, which can improve performance and reduce disk usage.
• Use efficient data storage formats: Use efficient data storage formats like binary or compressed data to reduce the amount of disk space required for storage.
