Storage performance is done using CrystalDiskMark version 5.2.1. Each drive tested will be securely erased prior to executing the test, while a reboot will be done between each round of testing. Testing the SATA connection, we will use a SanDisk Ultra II 480GB SSD, with a rated speed of 550MB/s for Sequential Read, and up to 500MB/s for Sequential Write. The M.2 interface will be tested with Kingston’s HyperX Predator 240GB drive, with a rated speed of up to 1400MB/s Sequential Read, and 600MB/s Sequential Write. To test USB 3.1 Gen 1 we will use an external USB 3.0 hard drive dock along with the SanDisk Ultra II SSD.
USB 3.1 Gen 1
Storage Performance Results: Storage performance is a bit of a mix, for SATA and USB 3.1 Gen 1 it lead the pack in both Sequential Read and Write. For M.2 performance, that was reversed and was close to 100MB/s behind the leader of the Z270 motherboards for Sequential Read. For Sequential Write, the MSI Z270 XPower Gaming Titanium, was just 1.2MB/s behind the lead motherboard.
