Games on same SSD as OS?

post #1 of 9
Thread Starter 
Hey all,

I've just bought a Samsung 830 256GB as I am running out of space on my X25-M. Obviously the 830 is a much faster drive - I don't need to tell you this. I am only running SATA 2 ports at the moment (waiting for the next generation of CPUs to upgrade).

I bought the other SSD to give me more space to put games on since Battlefield 3 is already like 40 GB and my 80 GB is just not cutting it anymore.

Now, I read somewhere that having games and the OS on the same SSD means that the games have to "fight for IO" with the OS. No idea if this is true or not - maybe someone can squash my misconceptions.

Will I notice that much of an improvement moving my OS over to the 830, or should I keep my OS and Programs how they are (on the X25-M) and just use the 830 solely for games?

Obviously it would make sense for me to move the OS over to the 830 when I get the SATA 3 ports from a new motherboard next year when I upgade, but I understand that with SATA 2 I won't notice that much of a difference for now?

Cheers

Stick games and OS on the SSD. Your Windows load times will be vastly improved. As far as games competing; i haven't had any problems at all, nor have i heard of anyone having any issues.

It is absolutely true - but keep in mind this is only a huge problem with HDDs. (Where fighting for I/O implies 10ms+ seeks in two directions wink.gif rather than 0.1ms) Some people with super high end setups have also noted the problem, but most of us with SSDs are actually CPU bottlenecked rather than I/O bottlenecked, so our SSDs don't actually get to perform to the levels that they can. When you load a game off your SSD, odds are your CPU is holding things up while it decompresses models/textures/etc... I've seen lots of game loading benchmarks where the MB/sec processed is in the low 20's or 30's, while most of these SSDs should be able to manage 200MB/sec+

I wouldn't worry much about it.

this, mainly an issue with HDDs, possibly low end / crappy SSDs.

Is this a scenario in which an 8 core Bulldozer would excell over an i5?

The question is in regards to clear cut scenario. The fact of the matter is that it really doesn't matter. Even with your computer now, I don't think you would be noticing these effects. Even at that, they slow your game down by MAYBE 1-2 FPS if you are unlucky.

Seriously the last time I ever heard something like this having a serious impact on performance was when my dad bought Myst when it first came out, and it was having some pretty slow frame rates. It turned out the hard drive was SUPER slow among other things.

Thanks for the replies. I'll rephrase the question in light of finding out that I/O would not compete with games:

Is it worth bothering moving Windows (either with a fresh install or using Ghost) over to the 830? I know it is faster but will I notice that much of a difference?

Once I get rid of BF3 from the SSD I have now there should consistently be 40-50 GB free on the OS drive (if I keep Windows and programs on my X25-M).

Doubtful. A lot of game engines still have single-threaded loading code. Many don't even bother having a second thread to manage user input - in a lot of games, you can't alt+tab during the loadscreen for long periods of time. (Perfect example - TF2)

I wouldn't bother. Too much effort for too little gain. Wait until you've got a SATA3 motherboard and then do it.
