Is this gaming laptop good for playing sims 4

@gabbymck1028  The SSD and HDD are both storage, and internally, they'd just show up as two drives; you could move files to one or the other as you wished.

If you're looking for more general info, there are a few different kinds of hard drives, with different read and write speeds.  The slowest are mechanical drives (HDDs), which run slowly enough that you'd notice longer loading times in most games: it takes a longer time to read from or write to these drives no matter what kind of data is involved.  But HDDs are cheap and reliable, so they're great for bulk storage.  It would be fine to keep, for example, your movies or music on one—the content would play back the same from any drive.

Solid state drives come in two types: SATA (fast) and NVMe (much faster).  Relative to the faster type of HDD, a SATA SSD might be 3-4 times faster, and an NVMe SSD around 20 times faster, although a lot of applications (including most games) won't take full advantage of the NVMe speed and will probably run just as fast on a SATA SSD.  The MSI has an NVMe SSD, which is where Windows will be installed, and you'd also want to install any game that requires a lot of loading on the SSD as well.

512 GB is plenty of storage, so you should be able to fit Sims 4, Apex, and GTA 5 and probably GTA 6 on that drive; you'd only need to start moving files around if you installed other games as well.    You could certainly install Sims 4 on an HDD—loading times are short enough that you might not mind the extra delay.  Or you could move game content you're not currently using, like cc and extra saves, to the HDD and then back to the SSD when you start playing again.
