A huge thanks goes out to AnandTech reader Andrei and some very attentive Xtreme Systems forum members. I just got an email pointing me to this thread where one particular number from our OCZ Vertex 3 and Intel SSD 510 articles was called into question. The problem? The 4KB random read numbers for the Vertex 3 were supiciously high. The reality? They were incorrect. 

I was just alerted to the error and quickly powered up the SSD testbed to recreate the test. It looks like the original numbers were either run at a queue depth of 32 or accidentally copied from one of the runs of 4KB random write tests. Either way the number was incorrect and has been fixed in all affected articles.

The updated numbers don't change our conclusions. The Vertex 3 is still the fastest next-generation SSD we've tested thus far and it still maintains a random read performance advantage over the Intel SSD 510.

The integrity of our test data is something we all take very seriously here. Errors like these do you a disservice and hurt the reputation I've worked so hard over the past 14 years to build. I do hope this oversight hasn't negatively impacted your opinion of AnandTech - we aren't perfect, but we strive to be. I do apologize to all of you for the error and I will be restructuring how I run and record my Iometer tests to avoid this particular issue from cropping up again. 

My sincere thanks goes out to Andrei and the XS folks who helped track down the error and inform us of its existence.

    Some people are slave of an ego, and suffer a lot meanwhile trying to hide his faults.

    Other people are free, owner of his life, and are the people that you can look straight in the eye, and trust.

    Thanks for your liberty, Anand.

    Makes my C300 not look so shabby, heh. Reply

    Just plain unprofessional to mess up on such a simple thing!

    Thought you guys were professional!

    That it, this is the last straw! I'm going to CNET for my tech information!

    Just kidding. Errors happen, spotting them and fixing or having others point out the errors and resolving it in a professional manner is WHY we continue to come to this website.

    Thanks for the work you do on all your articles and reviews.

    I love Anandtech for being scientific, objective and accurate. Tom's is riddled with "rumors" posing as "news", then there are their "build" articles which are just shopping lists without any performance numbers to backup up their claims and for the most part when there are performance numbers the tests don't prove anything.

    Anandtech does it right and that's coming from an Engineer ;).

    No worries Anand, everyone makes mistakes!

    It's also probably best to mention in the articles that amendments have been made.
    I checked both and this doesn't seem to be the case so far.

    People reading user comments may be confused by some of the remarks otherwise.
    Plus it's just the professional thing to do...

    Thanks for this official mea culpa.

    As an owner of the C300 64GB (shell shocker for $99 delivered), I have to say... I LOVE this graph.

    Thank you.

    Mistakes are one thing. Actively ignoring ongoing major issues is another and more damaging disservice to readers. AT has said nothing about OCZ's Vertex 2 capacity and performance reductions. I cannot believe I had to go to Tom's Hardware to get that scoop. AT has said nothing about the C300's stuttering problems. I have to go through Crucial forums to get info on that one (no meaningful response from Crucial, BTW.) My faith in AT might return if AT actually gets out of bed with the manufacturers and reports on both the good and the bad. Reply

    I don't know when it happened but through some order of events I end up on your site every day. I love reading your insights analysis of solid state technology. Thank you for this valuable resource. Reply
