The new iPhones are more powerful than ever. iPhone 15 Pro users have the option to record video to external drives. Thanks to Drive Speed, you can now measure video transfer speed between your iPhone and external storage devices. This app verifies data transfer rates and storage limits for drives you connect to it.
Drive Speed supports SSDs, USB drives, and memory card readers. You can customize video format, frames per second, and duration. This app keeps track of historical transfer speeds over time. To get started, simply open the app, select your storage destination, and choose the test parameters that work for you (e.g. resolution 720p to 4k).[HT]
