For now I can only speak well of this disc. Silent, writing as fast as my other Seagate and Samsung drives (81 MB / s peak on large files in disk to disk writing, I never got better with other discs in my current setup). The small reserve would be about the usb3 outlet. It is not identical to that of my other discs. This is not a major drawback since the cord is included, but I would have preferred that everything is interchangeable. Furthermore I still 1GB before completing it, and often towards the end that things go wrong. I will come to rectify this positive opinion if it occurs
