Overview
The Storage Test evaluates your browser's storage capabilities and benchmarks performance across multiple storage APIs. It detects which storage mechanisms are available, reports quota and usage information, and measures read/write throughput for each API.
Modern browsers support several storage APIs with different performance characteristics. IndexedDB handles structured data at scale, the Origin Private File System (OPFS) provides file-like access with optional synchronous operations, the Cache API stores HTTP responses, and localStorage offers simple key-value storage. This test compares them side by side.
