Maybe it is best not to defrag every encountered hybrid or SSD -- according to some sources. Some other sources ok the defragging of such HDs. Personally, after bi-monthly defragging with Defraggler a couple of laptops' hybrid HDs, I had to replace both hybrids. Check with the HDs' manufacturers about their hybrid or SSD products before defragging.
@RolandJS : Very well said. That's why Defraggler warns / prompts when you choose to defrag an SSD.

Thanks & Regards. ...
