When it comes to storing all the stuff on your gaming PC, you have two options: cheap, slow, and spacious hard drives (HDD) or more expensive yet much faster (and lower capacity) solid-state drives (SSDs). A good SSD makes everything you do on your PC feel snappy. Programs pop right open. Files copy in seconds. Perhaps most importantly, your games will load faster, allowing them to run smoother with fewer hitches and hiccups.
