Jazz Disk Bench Pro vs Disk Test by Magic Benchmark

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.

With Disk Test, you can easily test your device's storage speed and also measure how fast your device will work with all types of external storage such as external drives, USB Flash Drives, memory cards, etc. This clever assistant will help you to effectively detect weak points in your workflow. Both your device and connected storage affect the speed of communication with the data storage. It's not just the technical specification of the storage itself that is important for proper function, but also how it is connected. In particular the quality of the cable used, the characteristics of the connected USB Hub, the parameters of the Hard Drive Enclosure, or even the Adapters used. The File System of your storage device is equally important in the process of achieving the maximum speed. All this can be a bottleneck for your daily work. With Disk Test by Magic Benchmark, copying larger data will never be a nightmare for you again.
