CrossPlatformDiskTest
Windows, macOS and Android storage (HDD, SSD, RAM) speed testing/performance benchmarking app
Back in 2018, I built CrossPlatformDiskTest (CPDT), a .NET-based storage speed tester that racked up 500k downloads on Android. It measured sequential/random reads/writes, memory copies, and more—nothing fancy, but it scratched an itch for benchmarking drives across platforms. Fast-forward to 2024: I decided to recreate it in Rust (a language I barely remember from a 2021 LinkedIn course) using Kiro. No hands-on coding from me—just prompts, reviews, and AI orchestration. The result? A repo called cpdt2 with 72 files, 13k lines of code, 246 tests, and even GitHub Actions for CI/CD. But let's break down the journey, because this wasn't just coding—it was vibe-coding while AI did the heavy lifting.

Project mention: Archived: Popular backend frameworks by performance benchmark ranking in 2024 | dev.to | 2025-07-05
It's essential to note that this comparison primarily focuses on backend frameworks and not on programming languages. Drawing conclusions like "Rust outperforms Java" or "C# surpasses JS" may seem valid from the data, it's a false conclusion from my analysis. For a direct comparison of programming languages, there are separate benchmarks available for that purpose (like this or that).
