Samsung 840 EVO read speed drops on old-written data in the drive - Page 289

post #2881 of 3279
I really do not understand the Samsung supporters here.

The facts are that nothing Samsung has done instills trust in them. Furthermore, the theories of what the issue actually is has never been put forth as fact by Samsung, only these same sites that proclaim the latest fix is godly have. And those sites I don't trust since last October because of this very fact (they miraculously figured out the reason of the slowdown for old files with their great theories).

As to the 'instant' upgrade in speed. I am even more skeptical than @Sheyster. Samsung has been known to fix benchmarks before and this would be old hat for them to do it here (simply tell the firmware to report the file as 'read', regardless of the truth).

For myself, Samsung has lost the little cred it had before, and it will be in the negative if this firmware proves to be as useless as the first one was and is for many. And no, I do not consider running the advanced optimization a 'fix' if the underlying firmware proves faulty. We already had MyDefrag and DiskFresh that handles that situation for us already.

I can't see that as even being possible in this kind of situation given the kinds of benchmarks that we are doing. Now, if the benchmarks were synthetic benchmarks like what's done by CrystalDiskMark I could see how that would be possible but we are doing straight, real-world kinds of benchmarks (SSDReadSpeedTester for instance) in which we are simply telling the SSD to "give me that file" similar to how things would happen if you were to say... open a Microsoft Word document. It's just a file read request, read from the beginning to the end. If the SSD was in fact saying "oh, the file is done reading, here it is" you would have major data corruption, the OS wouldn't load, nothing would load at all.

 

At least the way I see it, there's no way for the SSD to distinguish between an honest read of a file and the rapid file reading that we are doing in SSDReadSpeedTester. There's lots of other activities that rapidly read files in sequence much like SSDReadSpeedTester does including loading games. I know for a fact that World of Warcraft reads ton of data in when it's loading from several fairly large 1 GB sized files (C:\Program Files (x86)\World of Warcraft\Data\data). Where it puts them after it's done reading, I have no idea. I have a feeling that it tries to stuff as much as it can in system RAM for those machines that have 8+ GBs of RAM. My machine has 16 GBs so it could stuff a lot of data in it and be a very happy game.

 

And yes, I do know about how Samsung fudged some benchmark numbers. If I recall they were some graphics benchmarks back when the Galaxy S5 was released and yes I agree that was shady.

I'm pretty sure the samsung supporters that don't shut up are paid to annoy us, it's like that show with don cheadle and veronica mars. Instill dissidents who support their client to mess with everyone else. Parky said he was "done" with this a few posts ago... sure don't look done to me.

@trparky just cuz a company uses lawyers as a matter of course doesn't mean they have to be shady and completely the opposite of forthcoming. They certainly don't have to treat their customers like excrement. Patents LOL who the hell is gonna want to steal the patent for the 840 evo, and how could you believe that the patents weren't already filed and at the very least pending. Or they could just reverse engineer it like everyone else that steals patents. SSD builds are pretty freakin simple, it's really only the controllers that vary, and the 840's was clearly garbage during the long wait til D. Your logic is stupid. Your defense of samsung is stupid. And you lie, case in point, you said flat out you were done. Why aren't you leaving us alone?

FWIW I don't consider trparky to be a Samsung supporter. I think he's just convinced Samsung has redeemed themselves with the D firmware. Where I think he's flawed is in believing there is a firmware fix to low tolerance NAND. The problem is unfixable, it's just being masked.

No, that's not what's happening. His mistake is that he thinks you are interested in a discussion, but that's not the case, right? You are just stating your view, and that's fixed.

If i find out that this firmware has not fixed the issue in the next 3 months, i will never ever touch a samsung product in my life and i will do everything in my power to convince every friend of mine to never ever give money to samsung. I'm not putting up with a defective product, and I'm not BETA testing their hardware...

you got your money back why do you even care if he supports them....honestly I still have my evo and I probably wouldn't buy another however I don't condemn Samsung as a brand for the mistake...however they should do the same for the 840 owners..they are the ones really getting shafted here they have no update no "band aid" and no recourse fit refund due to age of the drives...that sure is garbage....but that said at least in the evos case they arent sitting on their hands with earplugs in screaming I can't hear you...like some other companies have done in the past and everyone still buys from them. We know you hate Samsung and their actions but we don't tell you to go away if we disagree with you...if anything whether you love, hate, or like me lie somewhere in the middle your opinion just like his is free to be expressed here...since the update I have seen zero drop in speeds since the first reboot...it may not be fixed fully and my drive might die sooner but to be fair any drive could fail at any time...most of them before their "life expectancy"...I don't condemn those who jumped ship early on and got refunds or people who still want to...no matter how great or how bad a product you'll alwsys have both sides of the coin you should probably learn to accept that now or always be pissed at someone on the internet wink.gif

The first fix and this last fix both had sound theory about the fault and the fix for it. But the problem is that Theory is not "fact" and that was clearly proven the first time. Only long term testing will show if its fixed. A site can and should only say that in theory it should be fixed now, time will tell in the long run.
To be clear, I said that it 'appeared to be fixed'. I was pretty straight in saying that since the performance restoration tool forced a rewrite of all data that the clock was restarted. That's not the case with this update.
