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.
