Assistance - Calling all Samsung EVO owners

I ran the fix about 2 months ago:

Improved at first but noticed far slower boot times again recently and the stats are dropping off again. Might see if overclockers will refund. Doesn't put me off samsung but i think i will give the new samsung ones some time before jumping on that boat.

I doubt your "far slower boot times" are anything to do with this issue.
 
This thread confuses me. Is the issue only with higher GB SSD's or all of them?

Any benches I have found of the 120gb evo have been right on par with mine.
 
Well I only have an ssd installed no HDD or other components to slow the boot. No new programs or other start up issues that I can find so something is causing the load times of windows 8.1 start up to be slower than it has ever been. Plus the boot times improved following the implementation of the fix. Now I am not saying there can't be other issues but with the evidence I'm front of me the ssd would appear to be at fault. I have borrowed a spare old c300 add so I will try setting that up to see if it is any faster
I have also tried a fresh install of win 8 with no improvement.

What size of SSD do you have for the Samsung evo?
 
500gb. Tbh it has been a very good drive and with a fresh install etc it does feel snappy...ish but as I said it just seems to drop off. At this point the usage is fine although the boot times have increased (not a lot, but where before I did not see the loading screen of windows 8 before desktop it is now up for a good couple seconds) it is still quicker than a HDD but it is the point that we all paid for a certain performance and for some of us we aren't getting it (even if only benchmarks show it)

I remember reading that a 250gb odd Samsung drive will perform 50% better than the 120, and then the 500gb actively performing better than the 250gb as well.

Im assuming this thread Is really fro 250gb and over now, as I have never had an issue.

Although based on what I have read, there really is a major issue with these SSD's in terms of degrading. Very disappointing.

guess i should run this fix as well then and see if it works where can i download the fix? would i be able to get a refund or exchange with OCUK? i bought mine on the 10 / 02 /14

here is my terrible scores again :P

here is the restoration tool

http://www.samsung.com/global/busin...tware/Samsung_Performance_Restoration_V11.zip

some people have said that a secure erase after restores full performance. this is what I did with mine but to do a secure erase you will need a OS re install

I now have 4 x 840Evo`s which have been purchased over the last year or so and I have yet to see the slow down problems and one of them is full of old files that have not been used for more than 6 months. I think Samsung no what the problem is but are not coming clean on this issue.

I have 2 of them so far and I ran the tool and a secure erase on the 1st of feb so far my results seem fine and stable but only another 2-3 weeks will tell

I ran the firmware/restoration update on a 120GB Evo yesterday. I ran HDTune first to see how it was performing. The answer was "badly". Lots of dips below 50MB/s.

The update restore it to where it should be, around 500MB/s.

Assuming that you have your SSD connected to a SATA II port, the HDTune graph you posted earlier does not indicate any serious performance deterioration.

My EVO is showing much worse read performance than yours, and it has caused an increase in boot time (of Windows 7), but I wouldn't describe it as "far slower".

Maybe your SSD has another fault that is causing the increase in boot time. I might be wrong, but I'd guess that it is something else causing the problem.
 
so are they saying we should run the restoration update again? or just wait for a new fix?

anything new they have said?

I max out at 270mb read and write on my ssd using sata 2 ports

270 sounds exceptional and is on the upper limit for SATA-2 but pushing an extra 30 for 300 - no chance. The gap is too huge and I've not seen it in my experience.

Just did a quick run of the evo I fixed the other day (SATA-2)

Code: 
# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3124 MB in  2.00 seconds = 1565.16 MB/sec
 Timing buffered disk reads: 790 MB in  3.01 seconds = 262.74 MB/sec

yeah, I was not expecting anything higher than that just that the sata 2 are better than my sata 3 as its using a poor marvel controller

I'm interested.

Did you get your's from OCUK ?

Have they offered a refund or an exchange ?
Click to expand...

They offered me a refund on both my drives. They did say they would assess on case by case. I got out while i could because i wonder if they can truely fix this. It may well be that the cell drift is too hard to compensate for in first gen tlc nand.
