Nope, they are not in RAID. I had the idea that I could use the second SSD to cache the green drive, to speed up the loading of the games I am currently playing. I thought ok, I may have 100/200Gb of game files but there's really no need to have all of that on a SSD ! So I just want a system that watch out which games I am playing at the moment and cache that. My green drive having a read speed of 80Gb/s and my SSD of 500Gb/s I would expect loading times to be 6 times faster, something I should notice. What do you think about that ?
There's a post here on romex's forum that suggest this is not the best way to go and I would be better with manually choosing the games I play to store them on the SSD and then have a 4Gb RAM drive and 64K block size. The problem with this proposition is the word "
manually" which doesn't appeal to me !
Here is the post: Tips needed to Create a Cache for PC Gaming My setup also have only 8Gb of ram, so anyway I cannot do RAM cache for the moment.
Your benchs are impressive. NVME+RAM Cache really gets to a totally different level !
As I am on a budget, then I would avoid NMVE cache or SSD storage for the time being, keeping to SSD cache and HDD storage. I should soon move to x99, so I will have 4x NVME available. Then for the future, If I get it correctly, I would buy a larger HDD for storage and the cheapest NVME I can get for cache. Does it sound like a good upgrade plan ? Can you feel any difference in gaming with RAM Cache ?
Thoose are the specs of my system drive:
