Thick vs Thin 3PAR 7450c and vSphere 5.1 Build 2323236

Hello,

I know this is tricky talk about thin and thick storage within vSphere.

Through my research I have done. The 3PAR storage creates its volumes as Thin to manage space. Which makes sense.

So, now if i create a VM within VMware with thick drives, do i gain something ? I should gain performance, right ? What about thin ?

Or, the fact that 3PAR creates its volumes as thin, having a VM with thick vmdk's will not make any difference ?

Thanks for your help,
