We tested the drive using the NTFS file system.
Crystalmark 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.
Using the ATTO benchmark we couldn't quite achieve the maximum quoted read/write speeds for the drive of over 500MB/s and 480MB/s respectively, managing 480MB/s for reads and 462MB/s for writes. The more stringent ASSSD benchmark reduces the read and write figures even further from the official figures.
While the 4K read figures aren't anything to get excited about, the 4K write performance is pretty good at a shallow queue depth and even better at a deeper queue depths as can be seen from the CrystalDiskMark 4K test results.
