[QUOTE="MacInWin, post: 1898277, member: 396914"] That helps. What I think you have is a cheaply made device that probably has three 2TB SD cards inside, or maybe just the guts of three such cards, minus the exterior packaging. They were probably "fused" to look like on 6TB drive, but the fusion has broken and now you are seeing the three individual controllers through the USB port. The pricing tells me it is a knock-off, probably from either China or Taiwan. A good 2TB SSD is more than the price shown in the website.
