Rolling Cache Size and Location

Hello,i have RTX 3080 Ti,64Gb RAM and i9-11900K

i have a question about rolling cache and it’s location folder.

what is the best rolling cache size for 50Mbps internet speed,altough i dont fly regularly within the same location all the time,but sometimes i do…i currently set the RC to 25 Gb…is that enough or should i increase or decrease it? and also if i want to increase it to maybe like 50+ GB,can i set the file location to HDD? my fs2020 folder is in SSD

The default settings are fine. Some people even disable the RC. I wouldn’t put the RC file on a HDD as that may lead to increased stuttering.
