cleaned the drive now i have around 90gb free, but its just a little faster and same ram usage.
always thought that that its not relevant how full drive is with ssd drives
i will try to use smaller project files (resize them before putting them in premiere) maybe it will help a bit
When i would buy another ssd, what speed should i choose?
current has
3,200MB/s Seq. Read
can i buy slower cheaper ssd?
premiere should be on fastest drive?
Maybe ram usage will be the same with new ssd, who will know that.
what ram usage do you guys have in premiere?
I'll Lay it out for you. Premiere uses RAM and CPU as much as it needs. It uses the GPU to playback non-rendered clips and to render GPU accelerated effects. However when all of that is happening, Premiere is Reading AND Writing to several things at once. If all of those several things are located on one drive, Premiere will be slow. It may try to use more RAM or CPU since it's working harder to read and write.
If Premiere is using 30% RAM, it's because that's all what Premiere needs. If you have a better storage configuration, it might even use less. Each of the components has a specific task to do, and all of your components are doing their tasks correctly, except storage. At the end of the day, no matter how powerful your system is, it is as strong as the weakest link, in this case Storage.
As for what SSD to buy? When I built my system, I bought the cheapest 2 SSD I found, it was 500gb Kingstone. One for the OS and all my software (To answer your questions, Premiere should be on the main drive, and the main drive should be an SSD), and the second SSD for the Cache files and exports (Plus some personal random files). DO NOT SAVE YOUR CACHE TO THE C: DRIVE.
And for the Media files, I prioritized capacity over speed. I bought 2x 2tb WD Black and striped them as RAID 0. I also place the project files there.
