SMR explained: Be aware that this drive uses SMR technology (Shingled Magnetic Recording) to achieve such high density in a small package. If you don't know what that is, think of how shingles on a roof are laid out partially overlapping each other - that is how the data is laid out on the drive platters. While this allows significantly higher capacities, it creates some complexity to writing. If the drive needs to write data in the middle of existing data, it can't just "place" it there like a HDD using PMR technology because other data also overlaps it. What it has to do is put the data in a temporary location, then re-write all the shingled data afterwards to the end of the track break.
