150GB 10k Raptor as OS Drive with 1TB Blue as Data?

I haven't updated my gaming rig in a while. The HDD is a 10K RPM Raptor 150GB. I was originally looking to replace it outright with a Western Digital blue 1TB WD10EZEX, which has nearly double the sequential speed and obviously way more space. However I read something to the effect of having the WD10EZEX as a single OS/data drive may not be the best idea because your game (or whatever you're retrieving) will be at the end of the drive while the OS will be at the front, causing quite long seek times. Apparently this drive is particularly vulnerable to that sort of slowdown.

So I'm wondering. If I cleaned everything off my current 150mb Raptor and used it for OS only while putting everything else on the 1TB blue would this mitigate the potential for the aforementioned delays? I know the easy response is just get an SSD for my OS but I'm on a budget and really want to use as much of what I already have as possible.

    You should opt for a separate data drive to your OS as it will improve performance as well as the life of your drive. For an OS/Programs drive you are really looking at 4k reads.

    An SSD is the top of the pecking order but will only really effect your boot times and your menu loads in game. Games are RAM heavy. Your raptor will be fine and you will have the same issues with space (for programs/games) that most gamers have with the popular 120(ish)GB SSDs - you will install games that you are currently playing onto your OS drive and store the rest (and games saves ect) on your data drive. Gaming does not require a lot of hard drive use, so unless you actually want to spend money just stick with what you have. You may spend an extra 30 seconds waiting for windows to load, or 10 seconds for your game menus to load - but that's about it (as far as performance effected by your choice of hard drive).
  2. The slowing down is a myth. If you don't want to throw away the 150GB drive and if you think its not slow enough to put an OS in it, then go with your second method, this way you can use both drives.

    When the OS has a dedicated hard drive, it's only tasks are to seek, read and write as the OS demands. Can you please explain how performance is not at all effected when the same read heads and platters are also tasked with the additional seeks, reads and writes of data storage and access?

    Also, I've yet to find anybody who is not satisfied that their OS drive is "not slow enough."
