is a wifi ac adapter speed affected by usb 2 vs usb 3

One thing to say is that apple using proprietary USB2 even on the iphone 12 in 2020 limited to 480Mbps theoretical maximum is an absolute travesty, to continue to cause such speed of transfer forum debates is horrific, considering when the first USB3 devices came out in 2010? is completely insane. ill see if I can conduct that test and report back(see below for Results)

also we need some people to conduct some actual practical measurements over iTunes using say an itunes playlist of music say a standardised 20,000 megabytes (20GB) in size via USB2 and Wifi AC and report back I would expect AC to win but you can never be sure overheads etc. When you say the read speeds on an iphone are 402MB/s I should imagine that figure would vary dependent on iphone model and capacity? also the files sizes involved lots of small files lots slower etc. In all likelihood with transfer overhead file sizes your likely to get much less than expected ? from USB2 You obviously understand the difference between bit and bytes just stick to one unit of measurement when comparing? I suggest MB/s because most transfer speed dialog measurements visible to the user are displayed in MegaBytes per second or if NVME Gigabytes but lets stick to MB/s and not bits which is most comprehensible to computer users rather than anything in bits?Ĭart manufacturers promoted the megabit measurement to make there cartridges sounded larger, which has managed to confuse data rate, size and transfer discussions for years. The correct acronym is Mbps stands for 'megabits per second' MBPS for megabytes per second is not in common use IMO though i think i understand what your saying - capitalised MB etc. Where are you getting capitalised MBPS from ? I quote wikipedia re USB2 theoretical maximums 'you say USB 2 actual speed is 30MBPS ? … where are you referencing this from? your trying to indicate the theoretical maximum of 60MB/s is halved to 30MB/s in practice.?

I suggest you stick in future to some to bytes Units throughout discussions rather than bits or showing conversions?

Highly Wrong?! 480Mbps is the correct theoretical maximum speed in bits for USB2 disregarding protocol transfer overheads? IPHONE LIGHTNING CONNECTOR- REAL WORLD ITUNES SYNC SPEED TESTS - RESOLVED
