Hi guys,
Not sure what's going on here, but hopefully someone has a clue? I have a Samsung 850 Evo 1tb SATA3 connected to Gigabyte UD3H Z77x mobo (intel sata 3 port) -- I ran some benchmarks and noticed that my drive is performing subpar. Read speeds seem OK, but write speeds are about half of what they should be. I'm pulling my hair out trying to figure out why. I have latest intel sata driver for my chipset (13.1.0.1058). I tried switching to Microsoft driver with no effect. The weird thing is that if I boot into safe mode, benchmarks are fast and fine. When I boot into normal Windows, then benchmarks are fast if I run them right away, but after a few minutes the write speed slows down. I checked task manager and my drive is not in use. I know this is my C drive but there's no way the OS is using half of the write speed constantly. I ran Samsung Magician and did all of their recommendations for max performance.
Screenshots of benchmarks in safe mode (normal i think)
Screenshots while in normal boot (write speed about half) - userbench shows my SSD performing usually in 5-15th percentile. Not good.

Anyone have any clue what I can try? Looking at other options besides formatting.
Thanks!
