I agree with the recommendation of a Crucial MX500.
However, if you want to keep the same amount of HDD space, make it a 1 TB.
Also, you can use Acronis True Image or Macrium Reflect to make a perfect clone of your current hard drive to the new SSD, so that you don't have to reinstall Windows. If you go that route, then buy a USB SATA enclosure, like this: https://www.amazon.com/Inateck-External ... WI06GSC9E3
Put the new SSD into the enclosure, attach it to your laptop's USB port, and use Acronis or Macrium to clone your hard drive to the SSD. Then you can open up the laptop, replace the hard drive with the SSD, and you should be able to boot into Windows without reinstalling anything.
