My rule of thumb is that if the latency of the slog (write latency) or L2ARC
(random read)
is 10x

I know these are designed with SSDs in mind, and I know it's possible to use
anything you want
Another data point - I used three 15K disks striped using my RAID controller as
a slog for the zil, and performance went down. I had three raidz sata vdevs
holding the data, and my load was VMs, i.e. a fair amount of small, random IO
(60% random, 50% write, ~16k in size).
