I agree
I agree it is expensive. I also wondered what the performance was like and if it was a 5400 or 7200rpm disc. Looked at the handy freecom url and saw datasheets and lovely pdf's etc - still none the wiser. Remarkably as USB3 is new the fashion again as its a USB device is to list the USB standards maxium ideal, with tail wind speed and no hint on the real world speed is taken on the pdf and datasheet by freecom alas. I was also unable to ascertain if as to the speed of the hard disc.
All that said I can't think of any funky TV's that have USB3 on them or indeed need them just yet. So for the price and possible uses i'd question that being a good use for it, given the cost.
Another concideration is that of the length of cable and your nice wallmounted TV might be happy but when you try to attach said drive might find it hanging halfway up the wall, so that is a factor to look at. No LED is nice and and all but not a major selling point given the advent of duck-tape.
I do like that it includes a power supply and is not a totaly bus powered version which is an issue with some USB3 drives plugged into USB2 I have found that run of the bus's power, though no idea if you can run it solely of the USB3 port without the external PSU.
All in all, it's nothing special and for the price you could get something that has a built in mini NAS.
Also the operating temperature seems not suitable for rooms with direct sunlight in the summer, just a thought but a max operating temp of 35c is not enough margin of error for the 2 day british summer in october we have.
