ASRock Z87 Extreme 6 Review (w/ 4770k / GTX770)

We measure the system USB 3.0 performance by using the excellent Patriot SuperSonic Magnum 256GB USB 3.0 drive, which we reviewed back in February this year.

These results are as good as we have seen – scoring 267 MB/s sequential read and 175.5 MB/s sequential write.

Due to the nature of this kind of flash, and via the USB 3.0 interface, 4k and 4k QD32 performance is substantially worse than from a native SSD drive across a SATA connector.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

The ATTO results are always lower in the write test, scoring peaks between 60 MB/s and 70 MB/s. The read tests are much stronger, scoring a peak around 260 MB/s.
