Measure storage performance with Jazz Disk Bench. Run a disk speed test on your device's internal storage or a supported external USB drive, then explore read and write speeds, random 4K performance and latency. UNDERSTAND YOUR STORAGE • Sequential read and write tests show performance when transferring large files. • Random 4K tests measure small-block performance in IOPS and MB/s. • Latency tests show how long read and write operations take. • Choose the test size and operation count to suit your storage benchmark. WATCH SUSTAINED WRITE SPEED Run a stress test and follow the write-speed chart as data is written. See how performance changes during a longer workload instead of relying only on a single peak speed. COMPARE DEVICE RESULTS Browse the results database and compare two devices side by side. Select results from the database or your own benchmark history to examine the differences. TEST INTERNAL AND EXTERNAL STORAGE Test internal storage by default, or choose a writable folder on supported USB drives and SD cards. KEEP YOUR RESULTS Save completed benchmarks in your history and return to their detailed results later. No account is required.

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.
