Do you actually saturate the 10gbits via spinning disks or is it more for the reduced latency?

- magicalhippo 5y agoWell ZFS is fairly good at caching, so while I might not be able to saturate the 10gbit/s from the disks directly all the time, it's still a noticeable jump up from "merely" 1gbit/s. So depending on which disks is hit, I can get 300-500MB/s for uncached data. However when copying to the NAS, it can saturate as long as there's room in the RAM cache. In sum it was a quite worthwhile jump in performance given the investment of about $30 or so, even if it's "only" 3x in some cases.
