LaCie Rugged RAID PRO 4TB External Drive Review

Out of the box the drive comes factory formatted as exFAT so for testing purposes we re-formatted the drive as NTFS and tested in both RAID 0 and RAID 1 modes.

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.


The official transfer rate for the pair of Seagate 2TB drives in the Rugged RAID PRO is 140MB/s each. In RAID 0 the drives in our review unit produced 259MB/s for reads (129.5MB/s per drive) and 266MB/s (133MB/s per drive) for writes when tested with the ATTO benchmark.
