AIDA64 Extreme provides home users with detailed PC system information, live monitoring, benchmarking, and stress testing. It identifies processors, motherboards, graphics cards, memory, and storage. Other editions address business and network administration. AIDA64 Business monitors more than 250 sensor devices for temperatures, voltages, fan speeds, and power draw; it can collect hardware and software inventories from Windows computers on a corporate network. Business reports can be saved in open formats or an SQL database, and audit snapshots can be compared to identify changes and trigger real-time alerts. It also supports remote monitoring and control, including administrative tasks and file transfers. Network Audit is limited to inventory and does not include remote control, remote monitoring, diagnostics, or benchmarks available in other editions.

fio is a free storage I/O workload simulator for performance testing and reproducing bugs. Its job files can define multiple threads, processes and files, with sequential, random or mixed reads and writes using buffered, direct or raw I/O. Tune block and I/O size, I/O engine, queue depth, target files or devices, and job count. Documented engines include Linux io_uring and libaio, POSIX asynchronous I/O, and synchronous read/write options. Separate engines support HTTP GET and PUT requests to WebDAV or S3 endpoints and access to Ceph RADOS and RBD. Verification options can check written data after a workload, including repeated burn-in tests. Results are available in normal text, terse, JSON and JSON+ formats, plus bandwidth and latency logs; terse output is intended for scripts, tables or graphs. fio supports Linux, Solaris, AIX, HP-UX, macOS, NetBSD, OpenBSD, Windows, FreeBSD and DragonFly. The HTTP engine supports direct I/O only at depth 1, with scaling through multiple jobs.
