The GUI in Settings>Advanced>Storage gives you a choice for where to put the system. Do you get a noticeable speed benefit to using SSD for the system?
I have 16GB SATA DOM for my boot-pool and use RAIDZ1 HDDs for my main pool. Which should I choose for system dataset (it is just 2GB in size) and why? It’s currently using the HDD, but I’m thinking I’d boost performance by using the SATA DOM for system. This means more wear and tear on the SSD, but isn’t that negligible? On the other hand, if moving the system to the SSD isn’t noticeably faster, then I should keep it on the HDD.
I have 64GB of RAM. and I’ve only got 10GB in use, so it’s never touching the swap. Is there any reason to have the swap at all or should I only consider if I ever run out of RAM?
Any reason I shouldn’t use gdisk to partition my SATA DOMs? For example, with a single 16GB SATA DOM, it seems like the boot-pool and system combined don’t use up more than about 4GB. The amount of over provisioning depends on the workload. So if my system is on the HDD there shouldn’t be many writes to the SSD, so presumably I can reduce the size of the boot-pool partition to 8GB or even less?
Thanks for your insights.
