Solid State Drives are a nice piece of hardware for PCs, but the downside is they can end up costing quite a bit for the drives with more space. The major upside is that they're a lot faster than regular hard drives. While SSDs can be costly, you can sometimes find some pretty good deals on certain ones and that's the case right now with a couple of SSD from Samsung. Specifically the 850 EVO III in both the 500GB and 1TB sizes, which are now on sale for just $149 and $299 respectively. These are normally set at prices of $175 and $340.
One important thing to note is that these are internal SSDs, which means they will have to be installed in your PC along with all of the other components, and won't be a simple plug and play solution like with external drives. That said, the drives don't come with any of the cables or screws you'll need to mount this drive on the inside of your computer, so that's worth keeping in mind when looking to buy one of these as you'll potentially want to make sure to have that stuff on-hand before installation. These are compatible with Windows Vista, 7, 8, and 10 versions of Windows, and they're compatible with Linux. They have a read performance of up to 540MB/s, and a write performance of up to 520MB/s, so they're pretty quick at booting up your data as well as copying or saving stuff to the drives. These are also 2.5-inch drives, so you'll want to make sure that they will fit in the drive slots you're planning to put them.
