Now that we're offering to store private app data on adopted storage devices, the performance of those devices is much more important to overall user experience. To help set user expectations, this change offers to execute a real-world benchmark on a storage device, returning a metric that can be used to compare internal and external storage. The benchmark is generated from the strace-instrumented storage access patterns of typical apps. A typical device completes the benchmark in under two seconds on internal storage, a UHS-3 SD card is even faster (!), but a very slow Class 4 SD card takes about 30 seconds to complete, giving us a clear signal. The measured benchmark numbers are logged along with information about the storage device, such as manufacturer, model, etc. Card serial numbers are scrubbed from output.
