![]() This is also lower than what I thought it would be on the other hand there aren't many individual large files, but rather many smaller ones which tends to slow things down too. In any case, I just performed a file copy from one internal hard drive to another (both 7200), with a sustained data transfer rate of about 106 MB/sec. Well that's a bit of a wake-up call I have to admit, I feel like a bit of a sucker for the big marketing machine. So it is more likely that the transfers you are doing are bottlenecked by the storage drives, in particularl, their sequential read/write speeds not due to the fault of USB 3. Now if you were to hook up a superfast SSD to the dock, & also had a similar speed SSD in your system, then the transfer process would be definitely faster, since both drives could read & write lighteningly fast. So for USB 3, don't expect speeds of 400 MB/s + since even though the data could be transferred at that rate, it cannot be read off the source HDD or written to the external drive at the same rate. I've already given the reason for this, the read-write speeds of devices bottlenecks the transfer process. Most of the USB 2 devices today max out at 30-35 MB/s. Actually, it is only today, 8 years after the launch of USB 2, that USB 2 devices are able to fully exploit this speed (even then, there are not too many which can do this). USB 2.0 has a maximum theoretical speed limit of 60 MB/s. ![]() You should remember that the data is transferred to the destination, only as fast it is being read off the source. I just started a straight file copy (drag & drop) from one hard drive to the Seagate in the docking station, but the transfer speed is very slow -> sustained copy speed of about 65-66 MB/second, which seems more like USB 2.0. The docking station is connected to my computer via USB 3.0. I purchased a Kingwin Dock-Master hard drive docking station, as well as a Seagate 1.5TB 7200 HD to use with it. Apologies in advance if this is not the right forum.
