USB 3.0 Micro B Cable
Have a rather short USB 3.0 Micro B Cable to my external drive and
looking for a longer one, if it was 3 meters would that impact transfer speeds? |

Sunlight takes 8 minutes to get here. Starlight could take 80,000 years. Transfer speed is the same. And when you call India for tech support, Raj isn't speaking slowly. |

Unless spliced by M/F adaptors a cable isn't going to be expected, reasonably, to be manufactured out of specs to cause errors. There may be, aside, other factors, such as a USB hub that operates a cable at different throughput specifications than the source input USB, presumably at standard USB MB specifications. As specifications relevant to cable length I might tend to doubt an overriding for, say, a 20-foot USB, 6M cable, than perhaps your proposed 3M. I have a 3M USB cable, near or perhaps more, for discrete computer-component, equipped with USB, Fx/effects processing on instrumental music. Likely an afterthought I purchased at some point, which works fine so far as control interface to the unit's parameters: an onboard microprocessor control loops, which effects a secondary loop comprised from sound instrument's analogue pick-up, also plugged into the unit. Not exactly, at USB2 and a few bits to turn on a reverb, say, type and depth, what the throughput demands are to USB3 limits across a SSD or USB3 flashstick, which, so I hear, can't get somewhat toasty hot in latter instances. Then again, what I paid for that standard USB2 3M cable should be entirely independent of form factoring the micrco-city of connection types;- Not much (nickel-dime on pre-Trump antipartisan, anti-Chinese tariffs), or something generally useful to at least test considerately bandwidth copy errors. Keep your existing cable, though. That you have external USB3 speeds is nice, something not given all cases over enduser dissatisfaction between newer USB3 docking stations, and what at least some brands may purport and have in fact to do. |

Someone at a trade show here, got to test his USB3 camera, with a cable manufacturer "active repeater" cable, to a length of 14 meters. That's not a passive cable. A passive cable would have checksums on packets, indicating corruption, and the result should be a retransmission - because if the protocol was not reliable, you would soon notice a corruption issue. Even with a checksum, that only adds about 3 orders of magnitude to the noise floor. The disk drive itself has its own background error rate. https://www.lumenera.com/blog/usb-3-...-you-really-go To a certain extent "shorter is better", but the person making the cables, should send them out to a lab that can do an eye diagram and verify the eye opening is correct. Whether manufacturers do this or not, the trademarked symbol a manufacturer might receive a license to use, could specify what has to be done to legally use the symbol. Whether the standards body chooses to enforce "good quality" in products, is another matter. There is probably a ton of rubbish on the market - we have no way of knowing without very expensive kit (storage scope with optional eye diagram software), as to how much loss the cable has at the (recommended) max length. The scope could cost $100K at speeds like that, and have rigid plumbing for the interconnect. You can go at least 300 meters with fiber optic cable, not that this matters, as it's rather inconvenient stuff to work with. Such a scheme can't be any cheaper than a dollar a meter, and the terminal units on the ends could cost an astronomical amount extra. Then there's also the issue of someone testing such an expensive scheme, for its impact on transfer speed. If nobody owns stuff like this, we'll never know. Paul |

SPDIF, red-laser optical transmission of audio to intermittent stages, DAC stages into vacuum-tube preamps, have been interesting. The board, itself generating the laser, is ASUS' contribution, PCI soundboards, to a "World of Economical HiFi". Whereas ASUS' own onboard DAC, though well received, would seem less than a capacity for raw SPDIF output, in mating CS8416 digital receiver chip for the final DAC analogue conversion (vis a mixer and vintage DBX compression unit) to a pair of final vacuum-tubed preamps for bi-amping). Considering audio in any traditional sense, this is in a newer cabling interconnection of "hybridized" digital computer interfaces to traditional analogue hi-wattage amps. At the lower-end cost denominators of HiFi, as a pro-SPDIF unit can run up into the thousands of dollars when engineering, rather tailoring digital sounds by preference to headphones. In any event, the fiber optical cables I handpicked, for the least costly of the lowest, of course, would expectedly have proved rather problematic, at least in a most common form, that being the square-plug S/PDIF connection variety;- I haven't worked with laser as a coax option on costlier DACs. The thing being with inexpensive laser cables, is the innermost laser-carrier conductive within the cable. The optical receiver mating, specifically, inclusive of such as laser splitters for branching out from one source into two or more laser cables. Inner-cable slippage is occurring, to where end laser refractions deflect from proper signal mating. By pushing on the cable, slippage can be observed for adjustment to where the inner-cable's laser actually ends, in relation to the cable plug, and how that is consequent, quite, to a female receptor wherein its destined for mating. Periodic randomness from pops and click is one fault, in instance of a DAC's synchronization occurring infrequently, to altogether a immediate synchronization failure fault. Much worse, altogether, whereby to judge a sensitivity factor, physically, than decently solid analogue jacks of yesteryear. On the other hand, although practically this is as much a "left field" endeavor, the results given to S/PDIF packet conventions over some DAC offerings are pretty sweet-sounding indeed. The CS8416 DAC is aureally an airier transposition, and, for one certainly within economical hobbyist pricing, nevertheless well worth a decided temperament to optical routing. (Two CS8416 equipped units may not, however, be engineered, nor branded, to hardly be expected to sound quite alike, but for, perhaps, characteristics similar to the CS8416 DAC, as opposed to other DAC designs.) |
