What CrystalDiskInfo does
CrystalDiskInfo is the flagship product of Crystal Dew World, a Japan-based open-source software project founded in 1998 and operated by developer Noriyuki Miyazaki (hiyohiyo). The company was formally incorporated as CrystalMark Inc. in February 2025, headquartered in Sapporo, Hokkaido, and remains a single-developer operation. CrystalDiskInfo is a S.M.A.R.T. monitoring utility that reads and displays HDD/SSD health attributes (temperature, power-on hours, drive status) to help end users predict storage failures. Its sibling product, CrystalDiskMark, is a disk benchmarking tool that measures sequential and random read/write performance using Microsoft DiskSpd as the underlying engine. Both products are built on a custom MFC UI library called Project Priscilla, support x86, x64, and ARM64 architectures, and are distributed in themed editions featuring mascot characters (Shizuku, Aoi).
The suite also includes CrystalMark Retro (legacy CPU benchmarking), CrystalMark 3D25 (3D benchmarking developed with the demo scene community), and the announced CrystalMark Eternal (a CPU benchmark compatible with Windows 95 and NT 3.51). The technology stack is differentiated by deep domain specialization in S.M.A.R.T. parsing and storage performance measurement, broad RAID/VROC support, and a 40+ language community translation ecosystem. Distribution is free under the MIT license via official website, SourceForge, OSDN mirrors, and Microsoft Store, with no paid product tiers.
The business model is freemium-donation: the software is free to use and revenue is generated entirely from voluntary GitHub Sponsors contributions ($10 to $1,000 tiers) and Microsoft Store sales. The customer base is a globally distributed, long-tail audience of PC enthusiasts, general consumers, and IT/data center professionals, with roughly 96% of downloads originating outside Japan. CrystalDiskMark is widely described as the industry-standard disk benchmarking tool, and the developer holds multiple consecutive Microsoft MVP for Developer Technologies awards. There is no external funding, no enterprise sales motion, and no disclosed revenue.
