Do I need to defrag my hdd if I use optane with it?


I was wondering if I need to, or even if it is possible, to defrag my hdd while using it in conjunction with an optane module?

Hello rdxlcti,

Thanks for posting in our communities. Your thread as been moved to Intel® Optane™ Memory support.

Once you enable Intel Optane memory, both Intel Optane memory and the accelerated SATA drive appear as one SSD volume to the operating system. As a result, the options for defrag aren't available.

You can find more information about Intel Optane memory features and requirements here:

- Overview and Requirements for Intel® Optane™ Memory


- Frequently Asked Questions for Intel® Optane™ Memory

EDIT: Just for you to know, defrag is not available since it is not required. The Intel® Rapid Storage Driver (used by Intel Optane Memory) takes charge of maintenance and garbage collection functions on the accelerated drive.

Best regards,

I'm in the same situation.

Optane + HDD = SSD (viewed by O&O Defrag).

I disabled Optane and I defragged my HDD and rebuilt it after.

I have to remove softwares. I have to "clean up" my HDD.

It will inevitably be fragmented.

My questions are :

- is this the correct method?

- How many times can I disable and reactivate the Optane memory?

- or no defrag. Optane optimises the system.

There is an information in Optane software:

"last optimization on xxx at yy:yy.


Nest optimization on ddd at tt:tt."

(sorry for my english. I hope you understand what I say/want to do).

Thanks a lot for your answer.
