Exploring SSD Performance In Battlefield 3, F1 2011, And Rift

Launching Battlefield 3

Battlefield 3 requires 20 GB of free space to install, which is more than double Crysis 2's requirement. However, only a small portion of that data is used to launch the game. According to the summary stats, the exact figure is a little over 300 megabytes, which naturally consists of pure reads.

Although this is one of the most visually impressive games launched in 2011, there isn't a ton of I/O involved in starting it. About half of all accesses are randomly organized, and most are 4 KB in size at a queue depth of one. Given that hard drives don't perform as well when they're confronted with random access patterns, even at low queue depths, we're expecting a quantifiable performance improvement when we draw our comparison to magnetic storage.

I/O Trends:

  • 93% of all operations occur at a queue depth of one
  • 53% of all operations are random
  • 42% of all operations are 4 KB in transfer size
  • 16% of all operations are 8 KB in transfer size
  • 11% of all operations are 16 KB in transfer size
  • 15% of all operations are 32 KB in transfer size
  • 11% of all operations are 128 KB in transfer size

    Makes sense. I'll install sw:tor to the ssd after i figure out how to make its 20GB fit on it lol... the rest go to the HDD...

    Good read. Thanks for being so thorough.

  • IMO, a WD Caviar Black or a Samsung Spinpoint F3 would have been a better test drive than the Green one.

    Thanks to all the reviews you made here guys. A couple of months ago I started planning my ssd purchase, and i decided to buy a Kingston HyperX 240gb bundle kit. I cant wait till it arrives. I have advanced computer skills, so many things I thought from personal experiences are published here, like I knew some games are more write dependant or read dependant from and HDD, and about the apps on the background on WIN7, and many many more. I already ordered my SSD, but its nice to have a serious review about ssds on gaming performance. Its all about the speed that the apps can be done by write/read on a ssd on the background that really matters, from this simple thing is that anyone willing to upgrade to an ssd can benefit with a smoother playable experience.

    Storage can actually make a difference in FPS in certain situations. Only put in 2gb or so of RAM in the test system and rerun Battlefield 3, and the difference in frame rates will be different between HDD and SSD as the game switches to secondary storage once RAM is exhausted.

    True, but it is much more cost effective to add more RAM to your system in that circumstance than to get an SSD large enough for your OS and a couple of games. With RAM so inexpensive these days there is absolutely no reason to be running low on it under any gaming scenario.

    Agreed with xyzqwerty, please do another test with faster drives such as wd black or the f3. Comparing the ssd with green version is like racing your turtle with the neighbor's hare.

    I'm a little confused why you would want to see that comparison. We established there was no diff between a slow HDD and a fast SSD. And you expect a difference between a fast HDD and fast SSD?

    He probably want to see that comparison on the "Hard Drive Performance Comparison" page, where is a big difference between SSD and HDD performance (the HDD up to 477% slower)
