AJA System Test vs Parkdale

AJA System Test evaluates drive performance so users can estimate whether a drive system can record and play back different resolutions and codecs. It measures read and write speed and overall throughput, including on network mapped drives. In its graphical interface, users select a test type, drive, video size, frame rate, file size, and connected video device. Results can appear in MB/sec or FPS with graphs. The report generator produces text results that users can copy into spreadsheets or other software, and result exports include text report, PDF, and SPX formats. Custom test profiles are supported. Workload areas also include PCIe bandwidth, AJA-device DMA, and combined disk and device I/O; PCIe bandwidth testing is part of the full version included in AJA Desktop Software downloads. The standalone Apple Store and Windows versions are listed as AJA System Test Lite v16.0 at free. The software runs on macOS and Windows, and AJA offers a download path that does not require signing up.

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.
