Jazz Disk Bench is a pro-grade storage performance measurement tool designed for SSDs, SD cards, and internal/external storage. Get accurate data on your device's throughput with industry-standard testing methods. Key Features: * Sequential Speed Test: Measure peak performance for copying large files (movies, games, etc.). * 4K Random IOPS: Evaluate system responsiveness. Low random performance is often the root cause of device lag. * Pro Stress Test: Push your storage to the limit with 2GB–100GB tests to check stability and "real" NAND speed after cache exhaustion. * External Storage Support: Fully compatible with USB drives and SD cards via custom folder selection. Benchmark Details: * Sequential Test: Reads/writes 16MB blocks sequentially. Perfect for testing raw transfer speeds. * Random Test (4K): Reads/writes 4KB blocks at random locations. This reflects how fast your OS launches apps and handles small files. * Stress Test: Sequentially writes massive data (up to 100GB). Ideal for pro users to test SLC cache size and sustained NAND write performance. Note: For external storage tests, ensure a stable connection and write permissions.

About

GravityMark GPU Benchmark

This app showcases modern GPU power by rendering vast real-time scenes. It offloads all scene management and rendering to the GPU, bypassing CPU bottlenecks. Recommended for devices with Apple A14+ and M1+ SoCs.

GravityMark GPU Benchmark demonstrates the capabilities of modern GPUs by rendering an enormous quantity of objects in real-time, utilizing GPU acceleration. We avoid typical CPU-based performance bottlenecks by delegating the entirety of scene management and rendering steps exclusively to the GPU. Apple A14+ and M1+ SoC are recommended for great results. The following resources are used in the benchmark: NASA visible Earth database, GEBCO 2020 grid, the HYG star database archive, ESO / Serge Brunier The Milky Way panorama.
