Usually green drives lower the ReadyNAS speed by about 10%. He is seeing more than that. Though the PC is also a budget-class green machine - designed for small size and environmentally friendly construction, and not for performance. The desktop drive may be also be limiting the speed.TeknoJnky wrote:fondy wrote:I just bought an Ultra 4.

these drives are not very performance oriented, that is very likely why the write speed is relatively slow.
for best write speeds you want higher performance drives, ie 7200 rpm, not green, etc.
Though it might be worth playing with the ethernet adapter settings for transmit.
Ethernet flow control should be turned on.
Some of the other stuff could be experimented with, and sometimes it can help. Note the current settings first though.
