The write isn't that surprising to me because it was about the same with the 4x 750 GB drives. The read speed is much higher than I was expecting. I don't remember seeing that kind of speed without jumbo frames. Jellen, did you go from a 2x drive configuration to a 3 or more drive configuration? You may have seen better write speeds because before you were just mirroring data. With 3 or more drives, there will have to be a parity calculation, which could explain the slowdown. The readynas might be faster with mirroring only... It is mirroring only, my previes Readynas was a Duo with two 500GB drives (Seagate) X-raid Fresh new NV+ with two 1.5TB (also X-Raid, or mirroring) and I see only half the throughput speed of the duo with its 500GB drives.. Read speed is around 27MiB/Sec on those drives (maybe faster in a 4x system) Kind regards Jellen

I think the duo might be faster than the NV? Have you tried the 500 GB drives in the NV or the 1.5 TB drives in the Duo?
