All storage testing will be done using the latest version of CrystalDiskMark. When testing a specific device it will be formatted prior to testing, and the system rebooted between each test. Testing of the SATA bus, we will use the SanDisk Ultra II 480GB SSD, that has a rated speed of up to 550MB/s Sequential Read, and up to 500MB/s Sequential Write. Testing of the M.2 interface, a HyperX Predator 240GB drive, that is rated for speeds up to 1400MB/s Read, and 600MB/s Write will be used. Finally, testing the USB 3.1 interface, we will use a USB 3.0 hard drive dock, and the SanDisk Ultra II SSD.
SuperSpeed USB 3.x
Storage Performance Results: In the various storage benchmarks, the EVGA Z170 Classified K performed as we would expect. It might not be the fastest for storage, however the differences in speeds were minimal with between a 2% and 5% difference in read speeds. At these speeds that little bit of a difference would hardly be missed.
