Well, darn, I was so hoping that with the T 7 there would be increased capacity, such as 4 TB!!! I love my T 5s and have several of them but really, really was anticipating that the T 7 would go to the next level, not just in speed but in capacity. Guess that's not going to happen yet..... In the meantime, I've been more than happy with the T5 and also the X5 Thunderbolt 3 NVME -- both are plenty fast enough for my needs and I'll continue to use them as I have been. I love the portability of the T5 drives, and they travel with me easily, taking up very little room in the computer bag.
I am glad to see that now they're offering the three colors in each of the three capacities, which is convenient for those who have several drives and need to color-code for whatever reason (say, image files are on the blue 2 TB, movies are on the red 2 TB, etc.).
When reading the description, I notice that they have also worked on dealing with heat, which is good -- sometimes when I've been doing a lot with a drive, it can get pretty hot to the touch.
I imagine that the faster speed will be beneficial to those who like to use these external SSDs as their boot drive, and also for those who like to be able to put their image files right on the external drive and edit their images in there rather than on their computer's internal drive.
