I have not been using Defrag at all for my main disk SSD but have been using Health Check most every time I shut down. Is this OK for my SSD health?
Maybe the authors need to have a special SSD section of tools or something clear. Thanks,
CCleaner, including Health Check, is fine to use with a SSD without problems.
Health Check simply removes junk files, removes unwanted startup items, and checks certain apps to see if an update is available.
It doesn't do any kind of defragmenting/optimising.
If Defraggler recognises it as an SSD (it sometimes has a problem determing the drive type correctly) then it's also fine to use as it will 'optimise' rather than defrg.
Windows built in drive defragmeter/optimiser will occasionally 'inteligently' defrag an SSD when needed. Which comes as a surprise to some.
It will do that automatically, see this for more info.
