Was pleased with the fast delivery, but for the price I had my first time was not expecting much. When data recovery should not use at all, only for reading and writing of disks that I had are from old computers still so, or I have a set-top box that allows the reading of HD only on LAN, causing me to but is too slow. But then I was pleasantly surprised. The power supply made a solid impression and otherwise the whole thing looked pretty neat. My surprise was perfect as everything worked from the very beginning. About SATA HDs I can say anything here, had no HD are open, but 3.5 and 2.5-inch IDE work fine with it. Writing, reading, formatting, just everything worked right away. The speed is quite fast. The recognition under Windows7 and Ubuntu Linux 10.10 works perfectly when a USB connection is made. At the current system, as well as at boot time. Driver I did not need. IDE and power connectors I had slipped earlier, the other way you should not do anyway. Since power supply is adequately dimensioned, it is not even warm. I highly recommend this part. Top performance, top price. My expectations were more than exceeded. Today I an old DVD burner BenQ DW1655 IDE turn connected, works flawlessly. This is clear to me: No matter what I connect to it, it will work.
