May 5, 20197 yr Hi, I've been using UNRAID now for 2 days and overall am quite happy with it. My system build has: Athlon 200GE 16GB RAM I've noticed that read speeds are extremely impressive and basically saturate my gigabit network at home. However write speeds are very dismal. It starts off very fast and then drops down to zero MBPS and then spikes up back to close to gigabit for a while then goes back to Zero. The transfer window graph looks like a Sine wave During the write phase I did notice that the CPU utilization is quite high. Would it be possible that the parity requires a bit of CPU horsepower to do? If that's the case then I may need to upgrade to another CPU since my server is mainly write heavy.

May 5, 20197 yr It will help a lot if not read write in same time happen at any disk. But this won't final solve the transfer in sine pattern.
