SSD Performance In Crysis 2, World Of Warcraft, And Civilization V

A Gamer's Guide To SSD Performance

SSDs cost a lot more than hard drives; that much is well-established fact. Depending on the drives you're comparing, the difference in price per gigabyte can be as much as 30x.

So why on earth would anyone want to buy a solid-state drive, then? Shave down Windows' boot time? Fire up applications faster? Accelerate file transfers? Sure, on all accounts. But if you're a gamer, first and foremost, you want to spend your money on the components that'll give you the best possible performance. And if that means giving up CPU or graphics budget to score an SSD, you want to know if the trade-off is worth it, right?

Storage TypeMagneticSolid-State
BrandSeagateOCZ
ModelBarracudaAgility 3
Capacity1 TB120 GB
Price$60$210
Price Per Gigabyte$0.06$1.75

That evaluation isn't an easy one to make, though. When you read through an SSD review, you typically see a handful of measurements that try putting performance in context compared to other solid-state and magnetic products. But you generally don't get any frame of reference when it comes to gaming. Those familiar metrics include:

  • 4 KB random writes
  • 4 KB random reads
  • 128 KB sequential reads
  • 128 KB sequential writes

But what do input/output operations per second and megabytes per second really mean to the enthusiast interested in knowing how storage technology affects the launch times and game play of the latest and greatest first-person shooter?

In the lab, we’ve already seen situations where dropping in a cutting-edge SSD doesn't have a big effect on performance. The reasons why aren't particularly complicated. However, we thought it'd be a good idea to break down the way three popular games affect storage performance in order to give you a better understanding of how they tax your storage subsystem. Crysis 2, World of Warcraft: Cataclysm, and Civilization V are all going to get tested.

It might surprise you to learn that the "one size fits all" approach doesn't apply to SSDs and it doesn't apply to games. If you want to better understand storage reviews when it comes to gaming, this information will help you make a more informed purchase.

    If it doesn't improve FPS I don't see competitive gamers adding SSD's to their rigs for nothing but main OS drive.
    Longer loading times are not crucial when all you want is to frag your enemies!

    This just confirmed what I knew already. I will probably upgrade to a SSD with my next build, but they are still so bloody expensive for the storage they offer. Plus, SSD are supposed to have better reliability compared to magnetic drives.

    If only SDDs were a few cents a GB...

    Doesn't this reduce the life of a SSD?

    I took WoW off my SSD for 2 reasons: space and performance. WoW is just way too big of a folder with addons and everything else it was around 35GB and like this article states the start and initial load is really the only benefit. Once you are in the world (of warcraft) it's not used.

    I'd like to see how the witcher stacks up with SSD. You are constantly having to load different areas the entire game so I made sure to have that on the SSD while playing it hoping to reduce the load times. Would like to see if that really paid off or not.

    It's all about the bottleneck, which isn't storage for actually playing a game. That said, SSDs are definitely cool, and I have one.

    a comparison with a 7200rpm hdd for example will be great.

    So it looks to me like game loading and level loading is not significantly hard-disk bound, if the disk is busy for such a short period of time. For example, loading a Crysis 2 level taking 58s, of which the disk is busy for 2.

    Does that mean if you had an infinitely fast disk, the level loading would take 56s? In which case, where is the bottleneck for level loading? Is it CPU bound? (if so, why isn't CPU usage at 100% when loading a level?) Memory? Graphics card?

    There was supposed to be a comparison with a 1TB Barracuda, but nothing made it into the article itself. How hard could it be to display two adjacent bars on every graph instead of 1? E.g. red for the SSD and blue for the HDD.

    Why don't we see how long are those loading times with HDD drive? Maybe we find out 2x faster loading is not worth 30x times more money per GB.
