Hi,
I was wondering what the recommendations are in regards using a separate SSD/NVME for the journal if also using a separate SSD/NVME for cache - is there any performance improvement, or would I be best just to use just use all my NVMEs for larger caches and not use a dedicated journal?
Thanks,
Will

For HDD, you should always use an SSD journal. Write cache does help some workloads but not all, you should test your workload to make sure you get benefit.
