The one I have in Mind the Intel one is it the best there is on the market at the Moment? Are they better than Kingston?
At the moment Samsung 840 Pro is the best. Intel was the best when they used their own controllers, and they have a new controller coming out to enterprise SSDs and hopefully will be brought down to consumer SSDs in the future, but right now they're using customized Sandforce controllers so I wouldn't put such a premium on Intel's quality for now.
Steam games that are installed on my SSD load very quick. However, the games from my Steam library that are installed on my HDD load normally.
Why don't you just install steam on the SSD and make a new library on the HDD? Steam itself barely takes up any space.
