A few days ago, the official Apple Lightning to SD Card Camera Reader upgrade to the 2015 version, compared to the 2012 version of the biggest change of course is to support USB 3.0 transfer rates, then exactly how fast? To be able to clearly see the USB 2.0 and usb 3.0 transfer speed gap, the foreign media on the iPad Pro iDownloadBlog recently conducted a hands-on testing, chose this because the current iPad also supports USB 3.0 is also the only iPad Pro.

Used as a contrast to the Lightning to 30-pin Adapter converter with a USB 2.0 card reader, transfer the same period of the Panasonic GH4 taken from 4K video to iPad Pro with an SD card, the video 3 minutes and 52 seconds long, the size of the is 2.8GB.

In the above video you can see, the new version of Lightning to SD Card Camera Reader took only about 47 seconds, and when used in USB 2.0 is up to two and a half minutes, the former almost four times the latter. Testing indicated that if use 2012 edition of Lightning to SD Card Camera Reader results then come and do the 2015 edition of the contrast would be more persuasive.

Future Apple might introduce more support USB 3.0 devices and accessories, but now will take into account the new Lightning to SD Card Camera Reader Lightning interfaces used on other devices only USB 2.0 speed, so the non-iPad Pro users upgrade little significance.
