I have TS-210 NAS and configure as Raid 1. After update to Firmware 3.6, I found the performance of copy file has slow down, even on 10.6.8. I have tried to upgrade my MacBook Pro to 10.7.4, the performance is more poor. It can only connect sometime and it will automatically disconnect. Even I have used SMB or AFP. Both has the same problem. I have tried to use Windows XP to connect. It has same problem also. I think that should cause from my NAS.
