Open Source Rust Disk Space Analyzers

Treemap disk usage analyzer: In search of lost space (a.k.a. wata-analyzer)

MangoDisk is a free, open-source disk cleaner for Windows, macOS and Linux. Find caches, large files, exact duplicates and app leftovers without digging through hidden folders. Explore disk usage with nested treemaps or a sunburst chart to see which folders take up the most space. Privacy Cleanup lets you review supported browser, app and system activity by time range. Clearing cookies can sign you out of websites. Also included: app uninstall, startup management, system optimization, common repair tools and an operation history. The resource panel shows CPU, memory, network and disk activity. Scans run locally and don't delete files. Choose what to remove and confirm before cleanup. No signup or login is required. Unsure about a file or an app? Optional online AI explanations cover cleanup items, startup entries, large files, duplicates and app uninstall. They explain purpose, impact and cautions; they don't delete files or replace your judgment.

Disk Speed Test is a lightweight storage benchmark for Windows, built as a modern alternative to CrystalDiskMark. It measures sequential and random read/write speed, IOPS and latency for SSDs, NVMe drives, hard disks, USB sticks, SD cards and network drives. Unlike CrystalDiskMark, which runs Microsoft's DiskSpd tool for each test, Disk Speed Test has its own native I/O engine written in Rust. Everything ships as a single small executable with no installer and no external tools. It uses unbuffered, overlapped I/O, so results reflect the drive itself rather than the Windows file cache. It offers the familiar tests (SEQ1M Q8T1, SEQ1M Q1T1, RND4K Q32T1, RND4K Q1T1) and profiles, plus things CrystalDiskMark doesn't show: a live throughput graph, latency percentiles (p50 to p99.99), per-run results and an optional mixed read/write test. Results can be copied or saved as text in the familiar CrystalDiskMark layout.
