Out of the box, the drive is factory formatted as exFAT. To run some of our benchmarks, we reformatted the drive to NTFS.
CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V8.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system's performance with various transfer sizes and test lengths for reads and writes. Several options are available to customise 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 manufacturer's 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 benchmarking 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.
LaCie's official Sequential performance ratings for the Rugged SSD4 are up to 4,000MB/s for both reads and up to 3,800MB/s writes. Using our test setup, the fastest read figure we saw was 3,110MB/s (CrystalDiskMark 8 Peak Performance profile QD8 T1) while the fastest write performance, 2,996MB/s, came from the CDM8 Default 0 fill test. The fastest 4K read and write performance came from the Peak Performance 0 fill test (QD32T16) at 1,078.01MB/s for reads and 1,109.22MB/s for writes.
