[QUOTE="SubliminalThought, post: 128373, member: 1503"] Agreed. Internal HD to HD will be capped at the write speed of your drives. Depending on your drives and configuration - on my Western Digitals in stand alone its around 130MB/s USB speed is capped to the the interface of USB and will get you around 40MB/s If you try to read two streams from the drive or write two streams to one drive it really affects IO. As you were copying from two partitions from the same HDD this was the case. What happens is that the drive head has to travel back and forth between the sectors for each partition as the copying is happening at the same time. This introduces the slower speed as well. If you have the drive in an external USB enclosure you will be limited by the USB speed. If your enclosure has eSATA, there is an eSATA port on the Microserver, but AFAIK its not Hot pluggable, meaning you will have to shutdown to plug out (or in) the external. [/QUOTE]
