    The benchmarks with AS SSD don't prove anything because it is testing read speeds with a fresh file it just wrote, so the "old/slow file" phenomenon won't show up in its test results.

Ok understood, ran your tool, analysis on performance?? My real world usage with this drive has been pretty good imo, I usually keep older files on my mechanicals.

    Looking at the graph, you can see that the overall trend is that fresh files read almost at 500 MB/s, with the speed dropping off to 250-400 MB/s at the 21 week mark (see how the trend of the graph starts high at 0 weeks and heads downward to the 21 week mark).  As many other of the 840 (non-EVO) results I have seen, the degradation in speed is a lot less obvious than with the 840 EVO, where speeds on old files could drop below 50 MB/s.

Non evo 840s are definitely affected too, I checked it on 2 samsung 840s (120 and 240gb, around 1yo), dramatical increase (like noticeable in real life even without benchmarks) in read performance after doing refresh.

I hope this is just the writer making that up. Otherwise Samsung is just completely incompetent.

They are quoting Samsung. So they are not testing for them selfs. Thats bad journalism to trust a biased party.

Samsung is just trying to save a few bucks on a EOL product and they will probably get away with it to.
The fact that it takes like 40-43 weeks for 840 to degrade to 50-30MB/sec and not 8 weeks or so like the EVO means that a lot less people are likley to notice it. Fewer users will have static data for that long reducing the chance of discovering the bug.

Samsung knows this its simple logic so they are just hoping to get away with it.

And by saying theres not a problem they will spread disinformation.
My posts in other forum with less enlightened users have quoted me saying that the 840 is not effected giving me the quote you just posted.
I gave them a how list of links to effected 840 users. They where quiet after that.

And they seem to miss that I created threads in that forum, a main thread like this where other 840 users also posted about the problem. Some people simply trusts companies more then other users that are experiencing a problem and has the prof to back it up.

So yea its simple tactics from Samsung. If I wanted to get away I would do just the same. But I hope most company's do like intel did with the 6 series chipset with the B2 stepping and did a total recall and paying all the expenses and intel did also offer any one that had a Sandforce 2 unit a refund if they needed 256bit encryption that was found to be faulty. Samsung just dont want to spend money if they cant see it returning them a good profit in a near future.

So that I know how to test for this on my drive, how am I likely to notice if I am affected?

Should I leave a file or two in the drive without moving them (without reading them either?) for about 8 weeks and then bench again?

Do the firmware update. All Samsung EVOs are affected.

Will the update protect/fix EVO drives 100% of the time?

Please link me

    IMHO, if they're going to abandon the 840, they should at least offer to upgrade 840 users (via RMA) to the 840 EVO that they have released a (hopefully permanent) fix for.  It will be interesting to see how this all pans out in the end.
