840 EVO slow down.

My 840 EVO seems to be allot slower after it sits for 2 weeks, I see there are other complaints and a firmware update. Is there going to be another fix in the future?

I'll need to watch the ansers on this thread. I hope that the answer is good.

I assume you're running AHCI and not IDE mode, right?

Can you be a little more descriptive?

What do you mean, 'sits for two weeks'? Do you mean powered off for two weeks then when you boot and get into Windows its slow?
Do you mean sit powered on and idle for two weeks without use?

What exactly is a lot slower? Boot? butt-dyno? Or do you have a benchmark to compare?

How full is the drive?

What other complaints? Links please...

I believe Samsung has Windows based software that will TRIM the drive etc. What does that software say about the health of the drive? What about SMART data?

You would need to ask that to Samsung, not us.

More info plz...not spitballing on this one.

Wouldn't it be slower out of the gate from this?

Did you already run Samsung's 840 EVO performance restoration tool?

AHCI is on. Powered off for 2 weeks, then I have to run 840 EVO Performance restoration. I did the firmware update, and I found these two articles. QUOTE Over the last month there has been some concern over the read performance of Samsung’s 840 EVO drives, and whether after Samsung’s previous performance fix, that these same drivers are starting to regress in performance once again. http://www.anandtech.com/show/8997/...0-evo-performance-another-fix-is-in-the-works QUOTE: The news of Samsung's SSD 840 EVO read performance degradation started circulating around the Internet about a month ago. Shortly after this, Samsung announced that they have found the fix http://www.anandtech.com/show/8617/...e-to-fix-the-ssd-840-evo-read-performance-bug

So..... how do you know you are getting slow downs?

Again......

The EVO Performance restoration works?

All the review sites are using HD tach for the 840 EVO and that is what I used. Mine looked like some of the reviews that I have seen. http://techreport.com/review/27727/some-840-evos-still-vulnerable-to-read-speed-slowdowns The EVO Performance restoration works however it is temporary from what I read from the links that I have posted and there are other sites that say the same thing. Mine looked like this graph http://www.anandtech.com/show/8550/...40-evo-read-performance-bug-fix-is-on-the-way

Please run atto and post the picture.

Edit: don't worry about it. If you say you have the problem, I guess you do. I'd reach out to samsung and see if you can rma or see what they say about it. You can ask if there is another fix.

The last thing I could find is another fix is in the works 2/20/15 Anandtech. Atto does not check the complete drive like HD tach does by reading every 32MB zone and every 8MB zone. Mine looked like this only it was 20 MB/S It looks like this with Atto now. Test with HD tach now.
