That configuration isn’t as easy to find as you would think on a portable drive. Ideally I would want to test the same drive that has both Firewire 800 and USB 3 built-in. That meant that I didn’t want to use two different drives. Since I couldn’t find the data I wanted, I decided to do my own tests. Most of what I found was comparisons to USB 2 or tests done before Macs had USB 3 built-in.

I did searches online and really didn’t come up with much in the way of current data or test. Apple is making the change in order to comply with European regulations that require electronic devices to have non-proprietary, common charging methods.Now that both the MacBook Pro Retina Display and MacBook Air ship with USB 3 I was curious to find out which was actually faster? Going with my existing Firewire 800 drives and the Thunderbolt to Firewire adapter or USB 3 drives. Thunderbolt 3 supports data transfer speeds up to 40Gb/s, so if Kuo is correct, there will be a major difference in wired data transfer speeds between Pro and non-Pro ‌iPhone 15‌ models.Īpple is transitioning to USB-C across its product lineup, and the first USB-C iPhones are due next year. USB 2.0 transfer speeds are limited to 480Mb/s, while USB 3.2 supports speeds up to 20Gb/s. With the upgrade, ‌iPhone 15 Pro‌ models will be able to transfer video files and other file types at quicker speeds, with Kuo predicting a significantly improved user experience. Kuo says that transfer speeds will likely 'improve markedly' on the ‌iPhone 15 Pro‌ models, with support for 'at least' USB 3.2 or Thunderbolt 3. My latest survey indicates all 2H23 new iPhones will abandon Lightning and change to USB-C, but only two high-end models (15 Pro & 15 Pro Max) will support the wired high-speed transtfer, and the two standard ones (15 & 15 15 Plus) still support USB 2.0 same as Lightning.
