I'm a newly registered member at this great website. Hopefully I'm posting in the right place.

I've had my computer and my Samsung SSD 840 for two months and it has worked really well until about a week ago. I noticed the issue when the computer started to lag a lot when downloading from steam.

AS SSD benchmark shows some terrible results. The sequential write score is 5.32 MB/s and the score in the Samsung magician software is bad too. I have no idea how this has happened. I've read around at this site and others, but haven't found a solution. Does anyone have suggestions on how to fix this?

My system:
AMD FX 6300
8gb ram
Win 8

I don't know how or where to upload screenshots here so I copied the MB/s results from AS SSD below.

Any help is much appreciated. Thanks in advance.

check to see that the ssd has the newest firmware and try using the drive clean up tool. look to see how much free space you have on the ssd. if the drive gets to a point that it filed there no room for the drive garbage and trim functions and the drive slows down on the writes. if there a bad chip on the drive you may have to do a low level formant with the ssd tools. I would try the newest amd drivers to see if there a damaged driver.

Firmwire and drivers are the latest and I've tried with reinstalling the mobo drivers. At a Point I was getting low on disk space, around 10 gb left I think. When I realized that I cleared a lot of space and have 55 gb available. I've also used the samsung tools to optimize the drive. All this was done Before I posted the benchmarks above.

have you tried enabling rapid from the samsung magician? I did that and my 840 pro got tons faster. Running at higher than advertised speeds.
