I am planning to buy a new PC that has a 12 TB hard drive for "random" data and files, no programs.
Now I also want a similar HDD to backup my files from time to time. The extrenal disk is usually at a completely different place than the PC, so from time to time I have to load everything that is on the big internal HDD to the external HDD. As you can imagine I need a fast connection if I don't want to sit forever. My current system is at about 4TB and needs nearly a whole day over USB 3.0 (top speed of 120MB/s for the newer disks, and about 80MB/s for older external HDDs).
Now my idea is to put the new Plate into an USB 3.1 Type-C enclosure.
Now here is my question: Are these kinds of hard disks fast enough, that USB 3.1 is an advantage, or would USB 3.0 allow fast enough transfer rates and it is simply the HDD that is the limit.
