Hello I am interested in buying a new computer. My main activity is copying files from the hard drives to removable drives. My main requirement is that the computer be a super-fast copier. Since I mainly use portable drives that support the USB 2.0 standard, I do not need a motherboard that supports USB 3.0 standard, but I want the computer to provide support in all of the bandwidth of the USB 2.0, in other words, that the copying speed should be 480 MB/s. The question is whether upgrading the PCIe to USB 3.0 or 3.1 will improve the speed of copying.
These two are contradictions! USB2 is SLOW, and nothing will change it. If your destination is USB2 ONLY, then this is the limiting factor! No matter what you get, it will never be any faster if using only USB2. Plain & simple
In addition to what sebus posted, don't forget that all maximum transfer rates are theoretical and seldom achieved in the real world. Theoretically, my USB 3.0 ports and drives should be 10x faster, yet my real world file transfer rates are closer to only 4x. Am I pissed? No, I realize it's theoretical and I'm damn happy with a 4x increase.
IIRC, USB 3 is downward compatible with USB 2. The interface just runs at the slower rate. If you buy a USB 3 MoBo, you may have problems installing a Windows 7. There's a thread around here about Windows 7 and USB3. If you're going to use Windows 10, then the driver issue is not a problem. @John: Yup. @Enthousiast: Got A link to that beauty?
If you getting a new pc, then odds are very good that it will have 3.0 usb posts and no upgrading from 2.0 is required 2000 euro's for that usb box....hmmmmm
Anyway maybe someone has a recommendation on what improvement I could put in the computer to make it at maximum speed that the removable device gives
The answers to the OP question have covered what I had to say on it. All I can add is that, however you may feel now about your narrowly defined requirements, when you buy a new computer you should also consider many more parameters, which will prove important in time.
That's a much better approach to technical life than me. Whenever I look at the actual download speed I get from my 'Broadband' as distinct from the theoretical speed I'm supposed to be at least approaching it just makes me mad.
If the host is fast and the device is fast, then your transfers will be fast. If the device is slow, then the fastest USB host in the world will not matter. The moral of this story: Not only do you need to pick a computer with USB 3 ports, you also need USB 3 compatible devices to achieve anywhere near maximum rates. The same thing holds true with Internet speeds. If the remote site is slow, you can have Fiber on your end and you will still be running slow. That's the reality of it.
Even if you have the right things in place the real world speed is still usually going to be lower than the purported one written on the label or body of the hardware.
