Game Loading Performance

I chose two games to show both ends of the load time spectrum. The first test is World of Warcraft, I'm simply timing how long it takes from the character selection screen to a fully loaded scene in the realm I've chosen. Fully loaded means no more popping textures or waiting for anything else to load:

The Intel X25-M does the best here, even slightly outperforming the X25-E thanks to a more consumer-optimized firmware. The two OCZ drives occupy the third and fourth places, followed by the rest of the pack. No hard drive can keep up here thanks to the superior random read speed of a SSD.

The Far Cry 2 test is simply running the default benchmark and timing how long it takes to get from clicking launch to the loaded level:

While the SSDs take the cake here, the VelociRaptor isn't far behind. Once again the two Intel drives take the lead, followed by the two OCZ drives. The Vertex and the Summit tie in performance.

    Anand, This is a great Article and a good story too.
    The OCZ story caught my attention that a quick firmware upgrade make a big improvement. From my understanding that SSD system designers try to trade off Space, Speed, and Durability (Also SSD :)) due the nature of NAND flash.
    We can clearly see the trade off of Space and Speed when SSD is getting more full the slower the speed (This is due to out-of-place write to increase the write operation and a block reclaim routine). However, Speed is also sacrificed to achieve the Durability (by doing wear leveling). Remember SLC nand's life time is about 100K write, while MLC nand has only about 10K write. Without considering doing wear leveling to improve the life cycle of the SSD, the firmware can be much simple and easy which will improve the write operation speed quite a bit.
    I echo you that the performance test should reflect user's daily usage which can be small size files write and may not be 80% full.
    However, users may be more concern about the Durability, the life cycle of the SSD.
    Is there such a test? How long will the black box OCZ Vertex live?
    How long will the regular OCZ Vertex live? and How long will the X25 live?

    This article was excellent, explaining several issues regarding performance.

    It would be great if the next article abou ssd addresses durability and reliability.

    My main concert is the swap partition (Linux) or virtual memory file (Windows). I found an post in another website saying that this is not an issue. Is it true? I find it hard to believe. Maybe in a real world test/scenario the problem will arise.

    I hope AnandTech can take my concerns into consideration.

    Best regards

    This is the first hardware review I've read from start to finish, and the time is well worth the information you've provided.

    Thank you for your honest, professional and knowledgeable work. Also kudos to OCZ, I'll definitely consider the Vertex while making purchases.

    As i read the article, i'm thinking of ways to slow down the down the degrading process. Intel is gonna ship x-25m 320gb this year. If i buy this drive and use it as an OS drive, i will obviously won't need the whole 320GB. Say i would need only 40 to 50 GB. I can make a secure erase (if the drive isn't new), made a partition of 50GB, and leave the remaining space unpartitioned. Will that solve the problem in any way ?
    Another way to solve the problem, would be a method inside the OS. The OS could use a user controlled % of the RAM memory, as a cache for those small 4kb files. Since ram reads and writes are way faster, i think it will also help. Say you got 8GB ram, and use 2gb for this purpose, and then the OS would only have 6gb ram for its use, while 2gb is used for these smaller files. That would increase also the lifespan of the SSD. Can this be possible ?

    In reference to SSD's, I have read a lot of articles and comments about improved firmware and operating system support. I hope manufacturers don't forget about the on-board RAID controller.

    From the articles and comments made by users around the web, who have tested SSD's in a Raid 0 configuration, I believe that two Intel X25-M SSD's in a RAID 0 configuration would more than saturate current on-board RAID controllers.

    Intel is doing a die shrink of the NAND memory that is going into their SSD's come this fall. I would expect these new Intel SSD's to show faster read and write times. Other manufacturers will also find ways to increase the speed of their SSD's.

    SSD's scale well in a RAID configuration. It would be a shame if the on-board RAID controller limited our throughput. The alternative would be very expensive add-in RAID cards.

    Anand, once again you wrote an article that no one else could've written. This is why I'm reading this site since 2004 and will always do. Your articles and reviews are without exception unique and a must-read. Thank you for this thorough background, analysis and review of SSD.

    I was looking a long time for a solution to make my desktop experience faster and I think I'll order a 60GB Vertex. 200€(germany) is still a lot of money but it will be worth it.

    Once again, great work Anand!

    It's referred to as "discard" in the kernel functions.

    It works very well w/ SSD's that support TRIM, like fusion-io's drives.

    This is the best review I've read in a very long time.
    Thank you very much!

    Great in depth article on flash based SSDs. I'm waiting for PRAM though. Reply
