Sometimes CCleaner can't work out whether a drive is a solid-state drive or a conventional hard drive. Why is my hard drive shown as a solid-state drive? Because of this, solid-state drives include functionality to spread the 'writes' across the hard drive, stopping secure overwrite procedures from repeatedly writing over the same portion of your hard drive. The number of times you 'write' data on a portion of a solid-state drive helps determine its lifespan. You can find out more in our article on Defraggler and SSDs. Note: We also don't recommend defragmenting SSDs due to the same lifespan concerns.

The Wipe cleaning function in Drive Wiper always performs a “1-pass” wipe, but you can set the Security option to run additional passes for solid-state drives, but we don't recommend this.
