The copy speed is simply cosmic for this segment. I copied 200 and 300 GB, where 200 are 30-70 mb files, and 300 are 300-900 mb files. The speed of copying small files is 90-120 Mb/s with drawdowns up to 80, the speed of copying large files is 80-100 Mb/s with drawdowns up to 50. The average copy speed is stable 100 Mb/s. 500 Gb flew to the disk in 70 minutes. Pros below: 1. Good and reliable brand 2. Rubber protection with reinforcement on the sides 3. HDDtoGO and OStoGO software from the manufacturer 4. Price per 1TB volume 5. High copy/read speed Different cons: Glossy plastic disc - not for everyone, but terribly easily soiled
