Out of the box, factory formatted as exFAT but to for our benchmarking purposes, we reformatted the drive to NTFS.
CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.
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.
AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
The specification sheet for the Extreme Pro only mentions a read speed rating of up to 1,050MB/s. We couldn't quite get to that maximum with our tests, with a figure of 1,027MB/s in ATTO and 1,026MB/s in CrystalDiskMark 7. The best write figure we got from the drive was 972MB/s when the drive was tested with the ATTO benchmark.
