Review on Crucial 2TB Portable SSD CT2000X6SSD9 by Jeff Shapiro

Crucial X6 4TB Portable Hard Drive: I copied files from my desktop PC to the Crucial X6 4TB hard drive, about 1.5TB in total. Initially, the speed was good, but eventually the copying speed dropped and is actually lower than that of a standard HDD drive. The first third of the task ran at a reasonable speed of around 250MB per second, and then for reasons I don't understand it drops sharply to a low speed of 50MB per second and stays there until all the files have been copied . Speed was ok. Additional Cons: No activity tracker. The cable is short. As for reliability, which is the most important parameter - so far so good.
