March 2025 update
I currently have 2597 plots spread between 4 harvesters. Due to heat I have had the Chia farm off for multiple days which doesn't help with winning blocks or for filling up the 2nd TR-004. Current storage consists of: Main storage is a 10 x 20TB machine running ZFS file system, raidz2 (1460 plots) Secondary storage is 7 x 8TB machine running ZFS file system, raidz1 (397 plots) Pi5 (8GB) + TL004 with 4 x 16TB drives running bftrs file system, raid0 (560 plots) Pi5 (8GB) + TL004 with 4 x 16TB drives running btrfs file system, raid0 (slowly filling - 190 plots) I have a I5-11000 machine as the full node. The good news is the Pi5 + TL004 seems quite scalable, that is its fairly easy to add another one and once filled can switch it over to being a harvester. I'm seeing average latency on the Pi5 harvester of 400ms and max of 1.5 seconds, so it seems able to handle the random reads. While one could use a rack mount system with tons of drives I don't think the returns are enoug...
