Would love to see this as well. Use case is to reduce power consumption privately running unraid servers. A read cache on SSD base would allow to spin down the array during phases where no client is using vm's, docker containers or files shares. This will reduce power consumption, especially with when many drives are configured. Power consumption in my configuration: Array of 6 drives, 8TB total and write cache (SSD). Expected power reduction approx: 10-20 Watt, depending on the distribution of the files within the array. Already evaluated howto copy frequently read files from within the array to a pool device, but gave up since the unraid OS mounts the drive array with noatime flag ... ;-( so no chance for "find -atime" ...)
