Their current &quot;default&quot; installation is pretty much a compressed clone of a disk image so the destination has to be the same size as their source this requires no skill to install what so ever.<p>They also have a normal Linux installation mode which you can use but it requires about the same technical skills as installing any OS.<p>Please note that Valve has a pretty damn good picture of how much storage people have, 1TB isn&#x27;t that big even for an SSD (you can get a sub 200$ 1TB SSD these days).<p>SteamOS is still in Beta I don&#x27;t see the size requirement (which isn&#x27;t a real requirement to begin with) to be a real issue considering current gaming hardware.
My steam library is over 11TB (not installed ofc) and I&#x27;ve seen bigger, most new AAA game releases are 30-50GB in size.
