Is USB 3 a failure?

I was just thinking,... my current PC doesn't have USB 3 but my new will (as soon as they release the P67 motherboards after the recall)

And i wanted to buy an external HDD docking station because i store a lot of tv and movies on drives and put them away until i want to watch something on them, this to limit wear and tear since data loss would mean re downloading a few terabytes.

I was thinking of buying this: https://oxyt.strefazysku.pl/index.ph...e4199ec35092c5

I have never used the eSATA would it be a good alternative to usb3?

It seems that no one has USB 3, it also seems very expensive and i'm reading from time to time about newer up and coming standards supposed to be better, so my question is: is usb 3 a failure as an standard? and if so why?

I have USb3, with a usb 3 hard drive. (the connectors in it are sata 2 tho, hard drive is sata 3)

and i get 130MB/s average with it

If you could actually find hardware that could operate at or near the speed of the USB 3 bus it might be worth having. As far as external storage goes, if it has a mechanical (platter and heads) hard drive in it, it won't come even remotely close. They don't even come close to USB 2 speeds at the moment. Even with a solid state drive I don't think you'll come close to maxing out the USB 2 bus speed. Personally if I had an eSATA port on my PC I'd use that before spending any money on adding USB 3 to my current PC. Also if I had to chose between adding a USB 3 card or an eSATA card, I'd go with eSATA. But I have hardware that could use eSATA and don't have anything with USB 3. I don't think its a failure yet, its too new and too early yet to pass judgment.

Hard disk drive - Wikipedia, the free encyclopedia
As of 2010, a typical 7200 rpm desktop hard drive has a sustained "disk-to-buffer" data transfer rate up to 1030 Mbits/sec. A current widely used standard for the "buffer-to-computer" interface is 3.0 Gbit/s SATA, which can send about 300 megabyte/s from the buffer to the computer, and thus is still comfortably ahead of today's disk-to-buffer transfer rates.
Universal Serial Bus - Wikipedia, the free encyclopedia
The USB 2.0 specification was released in April 2000 and was standardized by the USB-IF at the end of 2001. Hewlett-Packard, Intel, Lucent Technologies (now Alcatel-Lucent), NEC and Philips jointly led the initiative to develop a higher data transfer rate, with the resulting specification achieving 480 Mbit/s, a fortyfold increase over 12 Mbit/s for the original USB 1.0.

I got it wrong, what more can I say.
I still stick to my last statement though. I personally would still buy into eSATA before USB 3.

i got som old 7200rpm drive in an old lacie usb2 external chassi and i get ALMOST 30mb/s.
