Windows 7: Is USB 3 a failure?

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?

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.

+1 Premiere, There are mobo's with USB 3.0 other than the P67's but get that you are waiting for the P67's to be re-released.

I currently use e-SATA and plan to stick with that for quite some time. It works just fine for me.

Yeah isn't usb 2.0 at around 480 meg/sec cap?
Never seen anything near that on a hdd anyhow.

What kind of hardware would that be? Even a "normal" SSD cannot feed at 5Mb/sec.

Spinning disks can feed up tp 100MB/sec. That is about 2x the speed of USB2. SSDs go up to 350MB/sec which is appr. 7xUSB2 speed. And USB3 is appr. 12xUSB2.

That is 480 Mega Bits. The disk speeds are normally quoted in Mega Bytes which is appr. 10x the MegaBits. Any better spinning disk is faster than USB2.

That would be roughly a 60 megabyte/sec cap. That can't be accurate I've had sustained higher than that over 2.0.

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.
