Securely deleting a file

[nicknike]

Hi

I am generating a file on my HDD and when I delete it, it still resides on the drive as we know.
I believe that if I delete a file on my pci type SSD, and then Trim the SSD, any deleted file will be unrestorable.
Is this correct? If so, could I move a file from the HDD to the SSD, delete it and then trim?

Also, I have CCleaner installed. I have checked the 'Secure File Deletion' feature. Will this really work to make a deleted file unrestorable?

Thanks

Sorry i have no input or comments on SSDs. I'm W.D. spinner fan. You don't need speed when your retired LOL. Spinners are reliable and a huge cost savings/GB
