Planning to buy a third license soon as I just added a RAID-0 4TB array of 2x2TB HDD and want to back that with cache, but am on the fence as I already get better than 200MB/s write and 400MB/s reads, and already run extra risk with the RAID-0 so I am not sure if I want to add a cache on top of that, likely will be read only. In my third rate its just 14GB Ram with no SSD cache. On my secondary rig I have the HDD's backed by 14GB Ram and 58GB NVMe for a total of 72GB cache space in an L1/L2 config backing the drives. If you want to speed up access to a system thats all NVMe using primocache the answer is not to RAID the drives its to get more RAM and dedicate it as L1 cache.īut, if you have HDD in the system then yes, you woulc (probably) stripe out a pair of paritiions and then use the compbined stipe-array as the L2 cache for the HDD array. Though you *can* accelerate an SSD the impact is minimal, specialy when speaking of using an NVMe cache on an NVMe drive. ![]() Originally posted by Mamba Bajamba:Does anyone who actually uses Primocache have any useful information? Primocahe user for multiple years here.įirst question is are you using any mechanical HDD? That is where primocahe shines the most.
