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.

    Anand you didn't clarify very clearly what is the difference of naming between 510 series and X-25 G3.
    The introduction leads me to believe 510 is X-25 G3, or is it not?

    Is X-25 G3 going to use 25nm flash instead, so it's another drive? If so, when is the release date of that, and how do we expect its performance compared to 510 in this review? Will the X-25 G3 uses a custom controller?

    As the article stated, the G3 (whatever it is officially called) will be a lower-performance part whose aim is to bring lower prices and better reliability to more mainstream segments

    So I've been waiting for quite some time now for the new intel drives since the reviews in the past about how reliable and how long life an SSD has, promising that all of this would be better with these new generation drives. Although now I am faced with the potential "problem" of a 3Gbit bottle neck in mi macbook pro and as mentioned in the review above "these next-generation SSDs not only use 6Gbps SATA, they really need it." So where does that leave me? Should a go for a cheaper older drive which might be less reliable in the long run (but nobody really knows right?) or buy a new generation drive which might be suffering from a bottleneck? I didn't really understand why the new drives really need the 6Gbit SATA to function well? Can someone please explain or give me some advice.

    thank you

    Best right now would probably be an Intel G2 drive. Fast enough and very good durability.

    The next generation drives aren't really going to perform much better on a 3Gb SATA port than the current generation already does, plus you have the worse durability inherent in the 25nm NAND chips.

    Wow, so Intel has a gap in it's road map and goes the 3rd party route and brings us a product that is essentially slower than a consumer product (Vertex 3) from another manufacturer.

    They could have gone Sandforce, why not?

    Would love to see you run a traditional hdd through the new bench so we can see what sort of real world improvements can be expected from making the switch to an SSD...

    Great article. I'll be waiting for the x25-m G3. Keep on Intel about this!

    Thanks for the review Anand, but I am a little disappointed that there are a lot of synthetic benchmarks but no real world tests.

    By "real world tests" I mean separate tests for: booting into Windows; loading a web browser with 25 tabs of saved web page documents on the HDD; starting Star Craft and loading a map; copying a large amount of files to itself; running a batch Photoshop image transform job; starting IE6 from a stopped Windows XP Mode VM and opening a complex web page hosted on the local disk; running a intensive anti-virus scan on a specific (large) folder etc.

    I know PC Mark and SysMark are meant to represent these real world test, but as individual consumers we have different usage profiles and by breaking down the results into individual tests we can better work out which drive is most appropriate for us, instead of studying the synthetic tests and making an educated guess.

    Cheers,
    Ian

    Seconded.

    A lot of people are complaining about the performance of the drive, and I'd like to know how much of a difference it actually makes in real world scenarios. If this drive comes within 10 ms of a vertex 3 loading up starcraft 2, then who cares?

    If you read carefully the Anand Benchmarks does exactly just that.
