I just received my brand new Dell XPS 15 wich is supposed to have a 1TB disk along with a 32GB SSD disk,
Since the booting of the machine is terrible slow I looked for the 32SSD disk, but Windows filemanager does not show it.
Is it hidden or just somehow not active (or even present?).
Do I need to activate it?
It won't show under Windows - go into system setup and you should see it.
While the cache will speed up the hard drive, it's no match for a native SSD - and if the system came with McAfee, ditching that alone will speed up the boot.
