fio vs Parkdale

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.

Parkdale measures read and write speeds for hard disks, CD-ROM devices and network servers. Its three access modes offer different ways to run a drive test. QuickAccess checks sequential and random access with 4KB blocks and 32 concurrent threads. FileAccess reads and writes test data in a regular file through the filesystem; BlockAccess works directly with disk sectors and displays transfer rates over time. Users can compare and submit drive results on the Benchmark page. The Windows version has command-line options for the drive, file size, block size and log-file creation, and installation is available through winget and Chocolatey. Parkdale runs on Windows, macOS and Android, with the maker listing operating systems from Windows 11 through Windows 98, macOS 27 through 10.7, and Android 12 through 4.4. The free software is supported by donations. The maker says crash reporting and automatic update checks can be disabled; those functions send a unique non-personal ID and operating-system version, and IP addresses are recorded to distinguish usage countries.
