HDD's and OS. (Question)

post #1 of 9
Thread Starter 
Greetings

Let's say we have two HDD's and there's an OS in each one (it could be the same OS doesn't matter). We are running a heavy program in which timing and access speed is important, a game fits this criteria perfectly.

So what is better:
1-) Use the OS in one hard disk and install the game in the other.
or
2-)Install the game in the same drive the OS is held.

The other important factor, i imagine, is if the 2 HD's are the same or different. Let's assume both cases.

Hope i can get some answers for the above ideal cases. As for my reality, one HD is a WD green, as you probably know, it mostly speens at 5400 RPM. The other is an old Maxtor 160 GB drive, which i asume spins at 7200 RPM. What´s the best way to install a program according to the answer related to the above cases?

Is there a way i could measure drive throughput? Also do you happen to know how much difference could a defrag make? And if you can defrag in multiple tries because big drives take a lot of time.

Thanks for any answers or recomendations.

Generally the idea is to put whatever you want to access faster on the fastest drive. So on your faster drive you could put the OS, some applications and a few games.

Save the slower drive for things that don't need to be accessed faster like music, videos, documents, etc.

As for throughput, HDTune is fairly popular. There's a few things that effect the difference a defrag makes, though, like how much data is on the disk or how often you run defrag.

I agree with pololance.

My setup is a C300 SSD 128GB for Boot, Games and Apps I use daily (black ops and office, as well as software that fuctions better with more speed, like my video conversion and compression software.)

Installed on a 300GB WD Velociraptor is games I play less frequently, like my massive library of old games which don't benefit from an increase in hard disk speed noticably from SSD over the VR.

Media is stored on 2x 2TB WDEARS Green drives in RAID0. Because I has lots uv mofies.


I've never run HD Tune but my preception vs. my old setup is a speed increase about 2 fold with my SSD in charge.


Any more specifics about what your considering running?

Thanks for the HDTUNE recomendation Pololance. I see that at least it has a 15 day trial.

@Digitalone: Most intence things im running this days are just games.

But back to one of my original doubts. Lets say the 2 HD's are more or less the same performance wise and i want to run a game. Would it be best to install the game in the drive opposite to the OS? The logic being that one HD would be busy with OS operations and the other one with the running game.

Does it make sense?

It makes sense, but I don't think you'll notice enough of a performance increase or decrease to warrant that approach.

I would wager that it might even slow it down some. IF there was a boost in performance, I would assume that many more people would be using that technique.

My guess is that it might even be slower. To have games installed off the OS drive.

Now, if you put it into a RAID 0, you will notice an increase in performance. Is that an option for you with your equipment?

Sadly no. But you got me thinking a bit on that. I wonder if i could get a good RAID array for cheap. On one hand the energy consumption would be higher but i could detach the biggest drive i have and use it ocassionaly if i buy an enclosure, you know to just watch media or store some documents. And use the RAID just for games.

Is the performance increase worth it?

That's similar to what I do. I have an external I use for movies, but I have my OS and a few most-played games on my RAID 0 array. Is the performance increase worth it? Yeah, I think so, although you forfeit reliability with RAID 0. Something as small as a bad sector can take the array offline.

As long as you have an up-to-date backup and don't mind rebuilding from start if/when needed, then RAID 0 is the best performance increase without worrying about reliability.

Thanks for clearing that up Pololance.

Hmmmnnnnn... For what little i have been investigating it seems to unastable for me. I'll considere it if i mange to find some really cheap hard drives just to test how the RAID functions.

But right now coming from some lately PC problems i don't want to get into any more trouble for now.

Apreciate the responses everybody
