You can use CCleaner for Windows on SSDs:
CCleaner is designed to be compatible with solid-state drives (or SSDs), and you can use it on computers using these drives.
Some CCleaner functions can wear out SSDs:
We would not recommend using any secure overwrite procedure on solid-state drives, including CCleaner's Drive Wiper tool and it's functionality. This is because this tool is ineffective on solid-state drives and will wear them out much faster.
This is because of how SSDs work:
A solid-state drive's lifespan is largely determined by how many 'writes' any particular portion of the drive can take before failing. Because this is so critical, solid-state drives include functionality to spread the writes out along the drive - enhancing their lifespan and making it so that secure overwrite procedures cannot repeatedly write over the same portion of the drive.
Wiping or defragmenting SSDs with CCleaner:
Because of the concerns mentioned above, CCleaner's Drive Wiper tool is limited to only using a “1-pass” wipe on drives detected as solid-state drives. The Wipe cleaning function in Drive Wiper will always perform a “1-pass” wipe. The Security option can be set to additional passes for drives set as solid-state drives, but this is not recommended.
We also do not recommend defragmenting such drives due to the same lifespan concerns - you can find out more in our article on Defraggler and SSDs.
The CCleaner functions that can impact an SSD's lifespan:
- Custom Clean > Windows tab > Advanced group > Wipe Free Space
- Tools > Drive Wiper
- Options > Settings > Secure Deletion and Wipe Free Space drives
Why is my hard drive shown as a solid-state drive?
In certain cases, the software cannot determine whether a drive is a solid-state drive or a conventional hard drive. In this circumstance, CCleaner will assume that the drive is a solid-state drive for safety. Alternatively, it can happen that the drive is misreporting itself to the computer.
In either case, if you are certain the drive in question is a conventional hard drive, you are welcome to make use of the Security and Wipe functions in Drive Wiper, although the Drive Wiper will still be limited to “1 pass”.
