The new XD80 2TB version from Silicon Power is very interesting, since it does not come with the previous controller but retains the same internal product code. As we have noted from the test results, the drive trades punches in terms of performance with the 1TB version while blank, but when filled to about 60% of its capacity, it falls a bit behind. We think that this can be attributed to the Realtek RTS5762 controller, which operates differently but unfortunately not a lot of info is available online about it.
