USB 3.0 is here. It has a throughput of 5Gbps, which means you can transfer a 25GB file in approximately 70 seconds:

The first usb 3.0 device i will be getting will be a usb 3.0 high definition webcam:

Hopefully someone will make a 10TB hard drive to store all the video i'd make.

it may have the theroetical bandwidth to do that, but you'll struggle to find a storage device that will read from and, even more unlikely, wrte again at those speeds.

also, someone calculated wrong... 5Gbps is equiv to 0.125GB/sec which means more like 200 seconds to transfer that 25GB file..

1 Byte = 8 bit


5Gbps = 0.625GBps


25/0.625 = 40 seconds.


So obviously, they did do the right calculations but looks like we are still limited by the throughput of SATA which is around 3Gbps.


25/70 = 0.357GBps


0.357GBps x 8 = 2.857Gbit which sounds like a real world SATA throughput rate.

lol. i think i divided by 0.125 (1Gbps). should have been sleeping.

still, i've not seen too many desktop sata drives do much better than 100MB/s anyhow. 3Gbps is pretty optimistic most times.
