I purchased this card and expected to copy files from my C: to usbb2 external drive faster, and easily. it did not work right away. After I spent couple days, I found a trick: need usb2 cable to provide power for esata port to run, meaning I need both cable esata and usb connected to my external hard disk to get better speed when copy files. It's weird.
When I plug only esata cable from the card to my ext-hard-drive, there is no light on the enclosure indicating the disk is active, and no new disk found under device manage. I cannot copy files.
When I plug both USB2 and eSATA cables, the disk can been seen and confirmed under pci-bus (hardware manager), meaning the external hard disk can operate via the esata port.
Using the teraCopy tool (free download), I can see the difference of copy the same file: 30MB/s using USB, and 40MB/s using eSATA cable (also with USB2 for power supply).
Using Window7, copy files from C: to usb2 hard drive, the speed is around 12MB/s. While copy the same file from C: to another local D:, the speed is about 52MB/s. I expected this high speed when use this card for copying files to external hard drive using esata connection.
I will purchase another card, but not this model. I realized I get what I paid :-)
