Project Description

CrystalDisklnfo is disk utility that supports some types of USB connections, Intel RAID, and NVMe. If anything abnormal is detected, it will notify you by text or voice message, and it supports both HDD and SSD. In addition to information like model number, volume, buffer size, it obtains S.M.A.R.T. information such as how many times the power was turned on, the time length of use, and temperature to monitor the state of the disk.

  • Important Notice

Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations.

If you want to contribute to supporting the continuance of this project, please make donations by Paypal. Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. Your contributions will be deeply appreciated.


CrystalDiskInfoは、ダウンロードメニューから入手できる。作者のサイトからはインストーラ版をダウンロード可能だが、機能面での違いはないため、ここではポータブル版で解説する。 ダウンロード ポータブル版... Show How to Install

PLEASE!!! Provide us a way to do auto APM OFF. Everytime I turn on my computer, or even after a reset, I need to do that manually! Is very boring now after thousand (or even more) times as I been using this great tool for years.
Superb. Use it!
Just need an auto APM OFF now.
