Performance

For the performance tests we used:

• Samsung SP1604N 160GB 7200 RPM IDE
• WD Raptor WD740GD 74 GB 10,000 RPM SATA

The pictures show the transfer rate from beginning of the disk (left), to end of the disk (right). This picture displays the USB transfer rate. As you can see the USB interface limits the rate to about 32 MB/s (=256 MBit/s). For both IDE and SATA the Kama Connect shows outstanding performance, basically the USB technology is the bottleneck and not the Kama Connect.

Of course it is possible to transfer files directly between the HDDs if two of them are installed. Here the transfer speed goes down to 16 MB/s. Because all data has to go via USB from the source drive to the CPU, and then back via USB to the destination drive.
