Question

My usb hard drive cable it came with is a little too short will a longer cable affect its performance?

Answer 1

The maximum length of a standard USB cable is 5.0 meters (16.4 ft). The primary reason for this limit is the maximum allowed round-trip delay of about 1500 ns. If a USB device does not answer to host commands within the allowed time, the host considers the command to be lost. When USB device response time, delays from using the maximum number of hubs and delays from cables connecting the hubs, host and device are summed, the maximum delay caused by a single cable turns out to be 26 ns.[12] The USB 2.0 specification states that the cable delay must be less than 5.2 ns per meter, which means that maximum length USB cable is 5 meters long. However, this is also very close to the maximum possible length when using a standard copper cable.

Maximum Useful Signalling Distance

Although a single cable is limited to 5 meters, the USB specification permits up to five USB hubs in a long chain of cables and hubs. Consequently the maximum possible signalling distance is 30 meters, using six 5-meter cables and five hubs. In actual use, the last hub is a more convenient endpoint since some USB devices include built-in cables intended to directly connect to a hub, setting the maximum useful signalling distance at 25 meters.

Because USB is able to provide power for additional devices connected to the bus, a special type of USB extender cable was created which consists of a miniature one-port USB hub molded into one end of a 5 meter cable. These mini-hubs are fully self-contained within the cable, requiring no separate bulky hub device, and are as simple to use as plugging cables together, with each hub drawing power through all the previous single-port hubs in the chain. The bus power is limited however, so the most practical application is to use four single-port hub extender cables, one plain 5 meter cable, and then a powered multiport hub at the very end to support multiple additional USB devices.

Answer 2

Not really it will just be longer.

Answer 3

no as long as you don't go above a 15 footer

Answer 4

Nope

You MIGHT have issues should you go beyond the 5 meter IEEE maximum length....

Answer 5

what do  u mean affect its performence, the only performence in a external hard drive is the campacity, and a longer cable will NOT affect it

Answer 6

Nope.

Answer 7

It will not matter what the length is of the cable that you use. A USB is a USB, is a USB. You could use any 'ol 20 foot cable handed down to you from freecycle and it would not matter. Have a great day.  

Answer 8

Not at all.
