Firmware Update to Fix the Samsung SSD 840 EVO Read Performance Bug Coming on October 15thby Kristian Vättö on September 26, 2014 5:10 PM EST
A week ago Samsung acknowledged the existence of the read performance bug in the SSD 840 EVO and I just received a note that the fixed firmware is in validation process and is expected to be released to the public on October 15th. Unfortunately I don't have any further details about the bug or the fix at this point, or whether the update is coming to the 'vanilla' SSD 840 and OEM models, but I hope to get more details as the public release gets closer, so stay tuned.

Coup27 - Saturday, September 27, 2014 - link"Its still plenty of endurance for most users though."
Unfortunately here we have another problem. Because TLC has less endurance than MLC people think it's junk and they need MLC without bothering to read up on the actual endurance levels. TLC is fine for the vast majority of people.
hojnikb - Saturday, September 27, 2014 - linkIts fine, that entirely true. But paying the same amout of money for same performing drive but getting less endurance ? Yeah, i'm gonna pick a MLC drive, regardless if i can manage to wear it out or not. TLC drives are simply too "expensive" compared to MLC drives to actually make sense. I mean, if i can get MX100 for example for the same amout of money (or even less) than ULTRA II or EV0, you can bet which of those i'm gonna pick.
kgh00007 - Saturday, September 27, 2014 - linkNevermind write endurance, what happens if you leave the drive off for 6 months or a year, are you going to loose data?
Coup27 - Saturday, September 27, 2014 - link6 months, no. 12 months, possibly. Longer than 12 months, yes.
However this is an industry standard and not specific to SLC, MLC or TLC. JEDEC standards state that for a consumer SSD data retention is 12 months after being powered off. Enterprise this is only 3 months.
AndrewMorton - Saturday, September 27, 2014 - linkI hope that "October 15th" means they have isolated the problem, have a fix already, and it will take until then to thoroughly test it, rather than that the marketing department (or some-such) has decided that that is the date it *will* be released.
xwingman - Saturday, September 27, 2014 - linkThanks for your post! Will this affect this model of drive: Samsung 840 evo MZ-7TE120BW single unit version?? I'm pretty new to ssd's and this will be my primary ssd for the os and a few programs. I don't want to have to do a firmware fix and have it all messed up. Thx.
hojnikb - Sunday, September 28, 2014 - linkyes.
poohbear - Sunday, September 28, 2014 - linkyesssss! had this ssd for a month as my system drive and was bummed to find out about this problem! looking forward to the fix!
Roland00Address - Sunday, September 28, 2014 - linkWhy release it on a specific date either it is ready or not. I understand saying you need about 2 weeks but you can not predict these things down to the hour unless it is already finished
Don66 - Sunday, September 28, 2014 - linkIf most people who are complaining never would have looked at the bench marks, I wonder how many would have been crying foul?
I bought a 1TB 840 EVO msata and without looking at benchmarks never noticed the difference in speed.
One thing I noticed was heat. I have a fan over it and it runs very cool. There's a three year warranty and I back up my data regularly.
Unless it's a physical problem with the drive, just don't bench mark wait for the firmware update, chances are most people wouldn't even notice without some kind of program telling them that their data is moving too slow.
It's ironic a lot of the same (used to be) fan boys, are now screaming that their precious drives are doomed and that Samsung had better do this or that, or the shizza will hit the fan, most people's memories are short like microwave times and they can't remember a week later why they were mad to begin with...
Samsung will keep making ssd', sheeple will keep buying them based on all of awesomeness of the drives, and this will be non-news in a short period of time...
I didn't buy my drive because of the reviews, I bought it because the price was right and I wanted more drive space.
