Performance vs. Transfer Size

ATTO does a good job of showing us how sequential performance varies with transfer size. Most controllers optimize for commonly seen transfer sizes and neglect the rest. The optimization around 4KB, 8KB and 128KB transfers makes sense given that's what most workloads are bound by, but it's always important to understand how a drive performs across the entire gamut.

As ATTO uses compressible data, SandForce based drives have an advantage due to their real-time compression engine. There isn't really anything surprising here as the V300 is on par with the other SandForce based drives. Read performance at smaller transfer sizes has never been SandForce's biggest strength but the write performance is strong at all IO sizes thanks to compression.

    At least for me they are working fine at the moment (tested on my desktop and laptop). Can you try a different browser? We had some issues with our image server earlier today, although it should be fixed now.

    Intel RST drivers provide a bit better performance and are hence recommended when using an SSD.

    Cool, thanks! And the images are working for me now on all browsers.

    Don't the latest drivers get installed with INTEL Inf Update Utility?
    Do i have to download something else?

    Images not loading in Windows Chrome v26.0.1410.64m or IE9. Hitting "Click for full size" produces the error: "Internet Explorer cannot display the webpage... Diagnose connection problems"

    Yeah, not loading for me either. Anand is on it.

    I was about to post about that too ... Firefox doesn't load images from images.anandtech.com either.

    I'm enjoying the new Imagination Viewing mode on AT, I get to create all sorts of great article pictures in my head. :)

    Pictures aren't working for me, either. :(

    Sandforce drives are boring.

    Could have summed this up with, "If it's a Sandforce drive and it's by someone other than Intel, look at any other Sandforce drive's review and consider a 5% variance up or down. The end."

    See, I can review any Sandforce drive by doing this. Where's my checks, Anandtech? This was hard reviewing I just did here. I reviewed every Sandforce drive based on SF-2281 on the market in the last six months. That's a lot of checks I'm owed there. You feel free to swap out the brands and models on the drives and what not so they all fit.

    Also feel free to pay me in Samsung SSD's. You know. Actually interesting SSD's.

    Just dont go by the branding. Kingston uses SandForce controllers - SF-2281 which are very proming & thats why Intel is bundling their SSDs with SandForce controllers & believe they are amazingly solid in terms of performance & reliability. Initially most of the SSD makers had issues with the controller maker - SandForce due to firmware compatibities which are now totally resolved.
