I was on my PC using around 2% of my CPU when suddenly windows system assessment starts.

 

When it finishes, my SSD rating went from 7.9 to 6.8.

 

I do a benchmark and this is what I get:

I have 50GBs free, ACHI on, TRIM done, RAPID on. What the hell just happened?

How much have to written to your SSD so far?

The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.

Not sure if this will help: f0a1bf45c1.png

 

 

I am betting this is related to RAPID. My 840 Pro benchmark gets all messed up too with it enabled.

 

I have never  had this issue in about 2 months. And besides, I don't think its the benchmark if Windows detected a sudden change.

The Windows Experience Index is hardly reliable. I am not using Windows right now so this is the last screenshot I took with RAPID enabled.

After disabling it everything went back to normal.

 

After turning RAPID off and restarting, my results were:

I am obviously very concerned at this point.

I recommend verifying with third party tools such as CrystalDiskMark and HD Tune or even booting into a Linux distro.

hdparm -Tt /dev/sda/dev/sda:Timing cached reads:   13740 MB in  2.00 seconds = 6874.10 MB/secTiming buffered disk reads: 1528 MB in  3.00 seconds = 509.12 MB/sec
fstrim -av/home/owner/VirtualBox: 64.6 GiB (69366677504 bytes) trimmed/: 2.7 GiB (2846527488 bytes) trimmed

 

I tried your first suggestion and this is what I yielded:

Its things like this that make me wish I could walk up to Samsung and question them face to face. Is this some kind of ploy to make me buy a replacement?
