February 12, 20242 yr I have been trying to find out what is the best file system type to run on a cache drive. I did my own testing using the windows in docker template and ran crystal disk mark for benchmarking. All test are done with only the system and appdata shares on the cache drive with only the windows in docker container installed and exclusive disk access for both shares. I ran crystal disk mark in the default path and a separate test in a shared folder linked to the appdata share so one test is fully on the docker VM and one is outside of docker. I also included a test from before my unraid switch with a test on windows 11 baremetal for comparison from what I can see from the test is there is no real clear winner. ZFS reaches the highest speeds but is not a clear winner as the read speeds are a lower (on folder outside VM disk) when compared to btrfs and xfs. I do find it confusing why the test on xfs outside of vm disk has higher write speeds than the hardware can actually perform, I am assuming any speeds higher than the drives hardware capabilities is actually taking place in ram... didn't think xfs used ram?? what do you think?
