Split your SSD/HDD the simple way on OS X.

So if you have a dual hard drive setup (SSD/HDD), here's a quick tutorial of how to set it up so the whole system will feel like a SSD. It's actually pretty easy. So basically we're going to move your home directory (for me, it's /Users/jonnguy) to the "slow" drive, and have your applications and operating system (OS) on your "fast" drive.

HDD = "Hard Disk Drive"

SSD = "Solid State Drive"

So let's assume you have 2 drives:

1. SSD
2. HDD (or a high-capacity, slow speed drive)

It should look something like this:

Here are the steps:

1. Create a folder in your slow drive. Name it whatever you want your home directory to be. (Mine here is "jonnguy")

2. Open System Preferences, and locate "Users and Groups":

3. Click it and then click your name on the left:

4. Click on the lock on the bottom right, then type in your password when it prompts:

5. Now, right click on your name on the left column and then click on 'Advanced Options':

6. Click on 'Choose':

7. Find the folder you created in step 1 and click 'Open':

8. Click on 'Ok':

9. It should ask you to restart. Click "Restart".

10. Once you restart, it may have seemed like all the stuff you customized (like background and dock) have been reset. This is normal.

11. If you need to transfer stuff (like preferences), copy the stuff from /Volumes/SSD/Users/<your username>/Library into the new /Volumes/HDD/Users/<your username>/Library.

======================================================

If you have Steam and games, those games should be located in /Volumes/HDD/Users/<your username>/Library/Application Support/SteamApps/common. If you want those to be on the SSD instead, create a symlink with Terminal.app (/Applications/Utilies/Terminal):

ln -s /Users/<your username>/Library/Application\ Support/SteamApps/common /Volumes/HDD/Users/<your username>/Library/Application\ Support/SteamApps/common
