Settings Storage - Solid-state Drive

[filciprian]

Hello!
I am using virtualbox for a few years now and i am verry satisfied! I test programs and running virtual hosts and i want that everything should run just fine!
I am a little confused right now with this feature: In settings > storage > Solid-state Drive. My question is: I use SSD from samsung. The VirtualBox is running on Windows and I installed linux centos 7 on a virtual machine WITHOUT setting this feature (Solid-state Drive). I have to reinstall the linux machine with this solid-state drive function activated? or if i activate now (after instalation and some software installed in the virtual machine) everything will be like i fresh install already with the function on? As i read , this functions activates some features to guest. And i want to know if is better to install a fresh linux with the feature on (or activating after linux instalation and other software instalation is the same thing)
I use to test programs and really should everything be perfect. I just want to know if installing without the ssd feature is the same as activating after instalation.

Please help me! I apriciate!

As i read , this functions activates some features to guest.

Not quite. It presents the virtual HD as an SSD. That's all. If the guest has some features that have to do with SSD, then it's up to the guest OS to activate (or not) these features. For example, if you turn this feature on in a Windows 2000 VM, it's not going to make a difference, because Win2000 doesn't have a clue what an SSD is.

Of course, you should be aware that it doesn't matter what your host is using. I am on an old fashioned HD, but if I turn this feature on, my VMs think that they're running on an SSD.

I wouldn't know for sure, but I'm thinking that you shouldn't have to do a re-install. Here's why. Say you run on a classic HD. You clone it to an SSD. You swap your HD with the SSD. Now, your guest should theoretically know (I repeat, if it has that capability) that it runs on an SSD and adjust itself accordingly.

Don't worry, I deleted your other message from the "Windows Hosts" section.
