What's the point? 1 1

I was looking, I have not found: what may well justify such a price? Connected to a 5K last iMac cry to stratospheric performance, the conclusion is that, in my humble opinion, his only interest for a fixed computer does not lie in the flow or "performance" but simply assumed in the addition 3 Additional USB ports (to the 4 available on the iMac), one front rather convenient and jack in one place (even if the sound output switcher for Mac at the station, you have to use the audio configuration and noon because this does not happen automatically). For a laptop, this simplifies the connection and allows connection to a single device to eventually access two USB hard drives or other accessories connected to the station. Furthermore, the device is not self-powered and therefore transformer. Debit side, connected in Thunderbolt 2 directly on the iMac, the transfer of a 5.14 GB of data file on a USB stick 64GB gave exactly the same time as connecting the key directly to the computer . So I do not understand the point of this resort to multiply performance through the Thunderbolt 2 because if the technology is present on an external drive, so the plug directly into the iMac without using the docking station .. . Perhaps this me he escapes, but the least we can say is that the investment does not obvious. At this price, so aim for a multimedia hard drive or network storage for example.
