Storage Performance

All storage testing is done using the latest version of CrystalDiskMark.  We will format the specific device prior to executing the test, and will reboot the test system between each test.  Testing the SATA connection, we will use the SanDisk Ultra II 480GB SSD, with a rated speed of up to 550MB/s Sequential Read, and up to 500MB/s Sequential Write.  The M.2 interface will be tested with the HyperX Predator 240GB drive, with it’s rated speed o up to 1400MB/s Sequential Read, and 600MB/s Sequential Write.  Finall, the USB 3.1 connection will be done using an external USB 3.0 hard drive dock, and the SanDisk Ultra II SSD.

SATA 6Gb/s

Storage Performance Results: Overall, the storage performance tests were right as we would expect.  The one surprise was the M.2 performance, throughout the Z170 motherboard testing, the Kingston HyperX Predator M.2 drive was consistently in the low 1300MB/s range.  The Prime Z270-A blew past that and took it to 1461MB/s Sequential Read!  Considering that the specifications on the Predator M.2 is for 1400MB/s, the 1461MB/s score is impressive.

    My MOBO died after 2 hours…! What a joke Asus has become! Will never buy another piece of crap made by Asus.

    Which M2 slot did you use, and any BIOS setting changes. i’m trying to determine if the M.2_1 slot is X4 speed or if I need to use the M.2_2 slot and set the speed to X4 in the BIOS.

    • Steven Kean

      Would’ve used M.2_1 as that’s the primary.

    Do you know if I put a 212 evo cooler on here will it cover the ram slots?

    • Steven Kean

      Not entirely familiar with that cooler to be honest, my guess is that as long as you’re not using memory with high heatspreaders, it shouldn’t be an issue. Might be tight if it overhangs the slots, but my guess is that it would fit. Sorry not much help with that cooler.

      • Stu Bora

        Yes, it will fit without the heat spreaders
