again, it doesn't matter if someone labels fix is "brute force" or it appears not as pretty as hoped, fact is, it works. after a year with fix i haven't noticed any adverse effects any my drive is still at 100% health. so please stop your conspiracies, because if fix didn't work we would have known it by now.

I already explained why this is not to be considered a fix. If you dont believe me, test baseline read speed, unplug the drive for a month or two and retest again. If nothing changes, round of beers is on me thumb.gif

why would i do that? first of all keeping SSD unplugged for long periods of time affects ALL ssds from ALL manufactures. and even if what you are claiming is more true for 840 EVO, and speed does drop by few % if drive is unplugged for months, you can just run samsung speed restoration which takes a few minutes and drives will be back to full speed.

Its true, that it affects all types of flash, but MLC flash will need to be powered off alot longer to exhibit this than TLC.

And speeds can drop in the 10s of MB/s for EVO (or any 2D tlc based ssd for that matter).

The updated firmware should have the periodic refresh feature designed to prevent further slowdowns in active systems. That mechanism can't prevent performance degradation on unpowered drives, but it's unclear how long it takes the problem to manifest. I'm still waiting for Samsung to clarify a few details about the refresh routine, including how frequently data is rewritten.

So all of that is avoided by using the drive you bought instead of putting it in a drawer? Phew, crisis averted.

A bit of knowledge of how NAND works would make this issue quite clear. But obviously something like that is not to be expected of a typical samsung fanboy smile.gifthumb.gif

sounds just like star trek next gen where scotty came up with the crazy way of keeping his transporter energy pattern from degrading for 60 or more years
only 50% effective since the other guy died during the years

the article one or two we read that we're concern is if you have data on SSD like ext archival backup and left it disconnected from everything stored it in a nice cool n dry place
come back later to find it empty or degraded

hopefully xpoint will solve that problem and might become the perfect archival media next to floppies n other things the library of congress deem safe

it be crazy that I have to take the SSD and put it in something that would keep periodically refreshed with power so it doesn't degrade
and hope nothing bad happens to it until I need to take it out for use at a later time

It's not crazy. You archive on media intended for archiving, this is true of digital archival as well as analog. No one prints their family photos on tissue paper and wonders why they don't last as long as photos printed on archival paper.

If you are archiving digital information, use a medium intended for archiving.

lol the only thing reliable for digital info is paper tape or stone tablets
o.w. every couple to several years you have to transfer what survived on HDD to another set of HDD

i hope xpoint replaces that
even if I had to copy data from one xpoint to another with no loss of data that be great

is all wear n tear local to that drive meaning u didn't relocate Users or Temp or internet files dir to a 2nd drive?

my ssd 256gb 850 evo is coming to one year old in a month (10TB written)
the transcend m.2 is 14 mns old only showing 1% wear n tear since I relocated the OS wear n tear directories to 850 EVO

but I use both drives for some VM ware stuff

Not too old at all TBH, almost 6 months old & I'll be pretty unhappy if it is on it's way out. I do however let it handle all the OS's reads & writes, then a bunch of apps I have installed on it also. Do you think that could kill an SSD that fast? I'm gonna look into doing what you said you do cause I have a ton of HDD space to use & it makes a lot of sense. It just never occurred to me to offload some the read & write duty from my boot drive TBH. doh.gif

There is the possibility that my CPU's OC was not 100% stable, cause the 1st time it happened I raised my Vcore from 1.32v to 1.33v & it didn't happen again for a few days. Now I have dropped my CPU's OC a good bit on the cache side down to 4.2GHz uncore & am hoping that can help. I had it running 4.5GHz core & uncore, Vcore voltage at 1.32v, & LLC set to high for the last 3 months without issue, it even passed 6 hrs. of XTU's stress test! The thing that really sucks is when it happens the blue smiley error screen goes by so quick I haven't been able to catch the error it spits out, leaving me to grasp at straws as to the cause. I gotta figure out how to dump & read windows errors. That would probably tell me exactly what it is but unfortunately I am not that software savvy yet. Although I do figure it is most likely one of the two reasons I aforementioned, at least they would be the most likely suspects. Although the SSD comes up as all good with CDinfo & HWinfo64 when it's working & it has only disappeared after those 3 crashes? Gonna see what happens with my new settings for my CPU's OC, if the issue persists I'll just go back to stock & see if it still happens then. axesmiley.png

I guess with Samsung you have to wait 1.5 years before buying their SSD. First time it's untested NAND, next time it can be mass controller failure, etc. Then again, there always going to be corporate defenders because of buyers remorse, like for the 3,5GB issue.

I'd stay away from Samsung based on their 840 issues.
