hkatsura/AmorphousDiskMark ? reverse-engineered prompt

Build me a macOS app that lets me benchmark storage devices like SSDs, USB drives, SD cards, and network volumes, and shows how fast they read and write. I want it to feel similar to CrystalDiskMark, with simple buttons to run an All test or individual tests, and a dropdown to pick the target volume first.

It should measure both sequential and random performance, and show results in both MB/s and IOPS. Please include different queue depths so I can compare single queue and higher load testing, and let me change things like test size, number of runs, random or zero data, and how long the test should run. The results should be easy to copy as plain text, and the app should also have a nice visual output with bar style results. Make it work as a sandboxed Mac app and ask for access when needed so I can choose a volume to test.
