pretty good
How is the software?
This drive is very fast, the included software from Samsung is pretty good, including the imaging software which is fast and easy to use.  Beware trying to use USB to Sata adapters if your going to image a drive to this SSD. (like switching out your boot drive to this like I did.)  IF your using the included Samsung software, as I did, it will not recognize the SSD connected to any of the three that I have tried, but your mileage may vary.
