I bought the seagate expansion few days ago and share my experience as under the device has usb 3.0 support snd I doubt about its performance as file transfer takes max speed of 24MBPS only. Other features like auto backup to cloud is not functioning well and miss some files to upload. Style and design is good but not premium. Service support is not good and you struggle to create login id and set up online account. The seagate expansion is not value for money in my opinion.
