CentOS or Red Hat using external USB
 

hi guys, running or booting from external USB using CentOS or RedHat does it affect the performance of the OS?

anyone tried it?

usb1 or usb2 or usb3

the answer is YES
and usb1 or 2 a VERY big yes

usb3 ??? not so much but it will be slower than on an internal drive

If for some reason you want to run in that way, a system that copies itself to RAM is better: Puppy, Knoppix, Slax.

hi gurus, thank you very much for your advice.

I just actually want to use the USB booting for my RHCSA studies.

Don't have budget right now to buy for a new PC.

I would dual boot with CentOS 6.4
then upgrade to 6.5 once it comes out

cnet makes this very easy
or use the CentOS 6.x repo instead of the 6.4
and a normal "update" will upgrade you

Hi John, thanks for the idea.

Dual booting makes sense.

:)

You could also set up CentOS in a virtual machine on your computer, assuming it has enough RAM. Much less invasive than dual booting, and completely risk-free to your underlying OS (setting up a dual boot runs the risk of wiping out your current OS if the re-formatting isn't performed correctly).

hi suicadaleggroll, virtual machine is fine.

but if I will go for virtual I will not be able to practice Red Hat Virtualization Manager.

As of this moment, a virtual machine cannot run another virtual machine on top of it.

But maybe few years now it might be possible.
