On Sunday evening, ordered, delivered on Tuesday afternoon, unpacked, plugged in and ready for immediate operation, has already copied me this as I find cheap purchased is marvel of engineering the first 100 GB large amounts of data successfully. Wider otherwise reviews on this Trekstor DataStation, it was on my computer no problem, datasets that were larger than 2 GB to copy the preformatted FAT32 format. I have in the first attempt to copy more than 70 GB on this storage medium and at a speed of about 1 GB per minute via USB 2.0. I thought that was quite comfortable. I have it 5 stars because I am totally satisfied with this product and would recommend it without any problems. I am for over 3 years in possession of a 160 GB removable disk made by TrekStor, with whom I am still satisfied, in terms of reliability and durability of the product. If both products should hold more than 5 years, I forgive love again 5 star. If my new acquisition should go broke within 3 years, I would write a second review and remove a few stars of the awarded 5 stars here. Carsten
