To test the storage performance in our motherboard reviews I use AIDA’s Disk Benchmark utility built into their AIDA64 Engineer Edition software package and run linear read and write tests.
We run the benchmark tests on the SATA III and USB 3.0 as well as any other storage options available. For SATA III testing I use a Toshiba HG6 512GB SSD and for USB 3.0 an Angelbird SSD2go Pocket 512GB SSD. The PCIe capabilities are being tested by one of Intel’s amazing 750 series SSD 1.2TB PCIe drives.
