Davinci Resolve - slow ssd speeds

Hi guys, few weeks ago, i have built a new PC (7700K overclocked to 4.8GHz, MSI Z270, MSI 1080X, Corsair 32GB 3000MHz RAM, Samsung 960 EVO). When i try to make an optimized media in Davinci Resolve from my GH4 files (25GB, FullHD, 50fps, 100mb/s), it takes like one and half hour. When i open task manager during the process, it says 100% disc usage but only about 20mb/s read speed and about 10mb/s write speed. Is it normal or somenthing is wrong? I know this SSD can be much faster, Thank you for your answers. Adam

What kind of Optimized Media Resolution and Optimized Media Format do you use ?

Best,
Ole

Are you on Windows and if so, does the 100% disk usage still occur when Resolve is not open? I had similar issues last year which was unrelated to any application software, it was operating system related and a pain to solve.

Hi Ole,
i am using a quarter resolution and DnXHR SQ.

Hi Steve, i am on windows, but when the resolve is not opened, i have almost 0% disc usage.
