About:
Fio is a versatile I/O benchmark and stress test tool designed to measure and analyze disk and storage system performance. It supports a wide range of I/O engines, storage types, and workload patterns, providing detailed metrics for performance tuning and validation.

Key Features:

Supports synchronous, asynchronous, and direct I/O operations
Extensive workload generation with flexible configuration
Detailed reporting including latency, throughput, and IOPS
Cross-platform with support for Linux, Windows, and macOS

Use Cases:

Benchmarking storage devices like SSDs and HDDs
Stress testing filesystems under heavy I/O load
Validating storage performance in virtualized environments

Alternatives:

bonnie++ – Older benchmark suite with less flexibility and modern I/O support
iozone – Filesystem benchmark tool focused on sequential operations
