I have 2 drives the c drive is ssd and the d is hybrid has anyone used defrag on hybrid and if so how was the outcome.
Hi Roger, and welcome to Piriform.
I don't know much about these drives, but from what I've read, defragging would or could upset the "adaptive learning algorithms", (and that term is a copy and paste).
You don't say the maker of your drive, but from Seagate ...
Turn off Windows automatic defrag. Like SSDs, Momentus XT works best without frequent defrag.

I think your question probably needs some input from the Defraggler devs, or maybe one of the guys on here may have a hybrid, but in the meantime I hope that helps.
