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.

one of the best utilities if not , the best , to check the disk properties health and smart data for ssd's and hdd's for the previous over 10 years the only thing it is missing is the sector alignment check (how a disk is formatted against the data structure of the physical hardware ) this is the only thing that made me look for an additional software in the same lightweight scale , the as ssd benchmark

ディスクの情報を手軽かつ見やすく分かりやすく縦覧でき、また使い勝手がよくとても信頼性の高いソフトウェア。PCの状況に関知したい人には必携のソフトウェアだと思う。 あと暮井慧ちゃんかわいい(Kurei Edt.使用者)
