I should have used Secure Erase before I sent my Asus board back but I didn't think about it at the time. I was wondering if using Drive Wipe in CCCleaner would achieve the same results as Secure Erase. Asus say that Secure Erase helps bring back some of the performance that can be lost over time on a SSD. Surely it isn't anything much different to the drive wipe function in CCCleaner? Will using CCleaner to wipe free space (not the complete drive) improve it's performance?
