Sequential Read/Write Speed

To measure sequential performance I ran a 1 minute long 128KB sequential test over the entire span of the drive at a queue depth of 1. The results reported are in average MB/s over the entire test length.

Iometer - 128KB Sequential Write

Sequential performance is another story entirely. When paired with a good 6Gbps SATA controller (in this case the H67's 6Gbps Port 1), the 510 is only 11% slower than the best case performance of the Vertex 3. Compared to the worst case performance for the Vertex 3, Intel's SSD 510 is 22% faster.

The comparison isn't as strong over a 3Gbps interface. Bound by the SATA interface, OCZ's Vertex 3's worst case performance is actually no different than its best case performance in 3Gbps mode. As a result, the Vertex 3 is consistently 13% faster than the Intel SSD 510.

Iometer - 128KB Sequential Read

While the 510 isn't remotely competitive in random read performance, sequential read speed is within 5% of the OCZ Vertex 3 - without any real time compression/dedupe trickery. And over a 3Gbps interface the Intel SSD 510 equals OCZ's Vertex 3.

    I am not sure if I missed it, but will you do a price/performance for SSDs? For example, and Intel or Corsair SSD migth be the fastest, but if it has a good price/performance vs the fastest SSD then it's something that consumers might consider when getting an SSD.

    I don't have a clear "performance" since you have run many benchmark in there, but something like a "real world load" would be good to see. I may not want the fastest SSD, but I will be looking for something that has good over-all balance in performance, and not so heavy on the pocket...

    Woops, I missed "not" i.e.

    Intel or Corsair SSD might NOT be the fastest, but if it has a good price/performance vs the fastest SSD then it's something that consumers might consider when getting an SSD.

    I thought that's what the light benchmark was, more "normal" tasks that aren't super-abusive with the SSD. Reply

    Yes, light being "AnandTech Storage Bench 2011 - Light Workload".

    Either Light or Heavy depending on your use seems to be a combination of both random and sequential performance.

    As stated in the article:
    "I'll be sharing the full details of the benchmark in some upcoming SSD articles but here are some details:

    1) The MOASB, officially called AnandTech Storage Bench 2011 - Heavy Workload, mainly focuses on the times when your I/O activity is the highest. There is a lot of downloading and application installing that happens during the course of this test. My thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives.

    2) I tried to cover as many bases as possible with the software I incorporated into this test. There's a lot of photo editing in Photoshop, HTML editing in Dreamweaver, web browsing, game playing/level loading (Starcraft II & WoW are both a part of the test) as well as general use stuff (application installing, virus scanning). I included a large amount of email downloading, document creation and editing as well. To top it all off I even use Visual Studio 2008 to build Chromium during the test."

    What price would you use? MSRP? Newegg after MIR? Just pick a usage scenario that fits your usage and divide the score by the dollar amount of your favorite e-tailer... Pretty simple. Reply

    Why not have both? AT has used a price grabber in the past.

    Actually, where did that go? It started to break down on the old site, but I'd like to see AT put that part shopper back up.

    Realistically speaking, if you're buying computer components/peripherals, the function
    Retailer GetLowestPrice(Component component)
    {
    return Newegg;
    }
    would probably be better than the average price comparison site.

    To be useful, the comparison needs to consider RAID 0 setups. Reply

    It seems like the one true major difference between the Intel SSD 510 and the OCZ Vertex 3 is that one is available now while the other is only talked about in reviews. First to market is always a benefit for a manufacturer that has a decently performing product, though Newegg's markup makes early adopter's pay dearly for it.

    Of course, this leads to the important question of "when will the Vertex 3 series reach general availability?" I recently purchased a 120GB OCZ Vertex 2 for a new 2011 17" MacBook Pro and the performance is stunning compared to the stock HDD (it's my first SSD). I'm wondering if I should return the drive and just wait for the Vertex 3 because once you've gone SSD, it is so hard to go back!

    Thanks for the review Anand!

    Oh, another thing. Are we going to get an SSD State of the Union for 2011? I'm guessing you're waiting to finish the reviews of most of the SSDs that are coming out this year first... Yeah, I just answered my own question, I think. :) Reply
