Thanks again for the help. I can't seem to run diskspeed. When I try run default settings and remove the tick on ssds, I'm able to run, however it just hangs on waiting on the first drive. I have managed to get rsync to pull files onto the array at 1 GB/sec. Movie files etc. So I think it's capable. Just something screwy I'm missing.

Thanks for the Reply, I did notice that the mover kicked in. But i Still dont think that is the whole issue? I cancelled mover and have reset the stats for read and write, nothing is currently writing to anything other than parity. The speed jumps from 70 MB/sec down to 12 MB/sec. Im not sure where to start to diagnose this issue. I also have another system that I built today, a dell R720. the specs on this one are CPU E5-2643 @ 3.3GHz x 2 RAM 64 GB DDR3 multi-bit ECC Perc H310 mini in IT mode Running 2 x CT1000P3SSD8 (1TB) as ZFS with another 1 x CT1000P3SSD8 as Parity nvme 1TB cache ZFS Im confused if its a config error i have done, or if its the HBAs, or these 2TB SSDs, I know they arent great, but would expect more out of them then this?
