Hi Reg Alsoft may say that (given they sell the product), though this link may help more <https://discussions.apple.com/thread/4092213?start=0&tstart=0> Particularly this part /quote What you DONT need to do is worry about physical maintenance - "defragmentation" is pretty much irrelevant. /end quote SSD's don't store files the same way a normal spinning disk does. Just like you "can't" really do a secure erase files from an SSD. Once something is erased on it, it's gone. (Even if you boot off another drive, and try do a "secure erase" reformat of the drive, that option isn't readily available in Disk Utility,..or others,….). This is one of the reasons backups with SSD's are very important, as once files are gone,..they're gone. So data recovery is a lot harder (if sometimes near impossible).
