Over USB 2.0, expect speeds to fall dramatically – below 50MB/sec. Performance dropped by 7 – 19% depending on the dataset. It ripped through the scene files, but slowed down with the materials, averaging 246GB/sec read and 217GB/sec write.Īcknowledging that not everyone has a workstation with USB 3.1 Gen 2, we also tested over USB 3.0 with the Type A cable. Our 3ds Max dataset offers more of a mix, comprising 60 large scene files and 4,400 smaller materials, totalling 4.6GB. With 68 Revit files, totalling 4.6GB, read performance averaged at 396MB/sec and write performance 335MB/sec.
Transfer rates increased significantly when copying larger files. Because the files are relatively small (50k to 60MB) speeds averaged 105MB/sec read and 90MB/sec write. We immediately saw an improvement in read/write speeds of up to 12% when copying our 8.2GB SolidWorks dataset, which comprises 14,000 CAD parts and assemblies. The drive came formatted to exFAT so it can work on multiple operating systems, but we reformatted it to NTFS as it is known to give better performance, particularly with small files. We tested read/write speeds over USB 3.1 Gen 2 with three real world 3D datasets from Revit, 3ds Max and SolidWorks. It has a sleek metal rounded unibody design, weighs just 51g and comes with both USB Type A and Type C cables to support USB 3.1 Gen 2 as well as older USB interfaces. It boasts read/write speeds up to 540MB/sec and is available in four capacities: 250GB (£125), 500GB (£186), 1TB (£375) and 2TB (£739). If you’re fed up with waiting for your data, then it’s time to start thinking about an external Solid State Drive (SSD) and the Samsung Portable SSD T5 is a great example.
