Sims 4 on SSD?

@skullgirl111  My experience is a bit different: I installed another operating system on an external hard drive and left Sims 4 on the internal drive.  (Actually, I installed a few OSs.)  So it's not exactly what you did, but the OS and the game are still communicating over an external SSD connection.  Sims 4 runs great; I don't notice any performance hit at all.  However, my SSD is very fast and has an equally fast connection, so that's not surprising.

There are ways to test external SSD speeds, and if yours is slower than the drive itself, you might be able to get a better connector.  But there's not much point in trying until you've addressed the crashing (or EA has).  If you happen to have this issue:

there are workarounds available; see post 2 for a link.

@skullgirl111 Mine's on SSD also. I have two internal 2TB SSD's. I don't even have internal "disk" drives and mine runs just fine.

Sims isn't optimized for SSD's so the speed isn't much better than disk drives. I have other games that ARE, and they run like lightning.

But the game runs just fine.
