The write speed is not (only) hidden by Digitec, even on the manufacturer's page Sandisk does not give any information about it! The reason? The stick is incredibly slow when writing. Here is a test:

There are two graphs in the lower part to compare the speed, the second one shows the Sandisk Ultra Dual Drive Luxe with a write speed of only 29 MB/s. The test tiger from the same company, Sandisk, does not give any information. The test drive from the same manufacturer, Sandisk (Extreme Pro), has a write speed of 232 MB/s. If I calculate correctly, it would take an incredible 9.5 hours to write to the entire stick (1 TB). For this amount of data, I prefer an external HDD, e.g. the Samsung SSD T7 with a write speed of up to 1000 MB/s.
