Set it up this way:
1. Put the OS, your applications, and your accounts on the SSD (but see #2).
2. Keep your "large libraries" (such as movies, music, and photos) on the HDD. You will have to "re-direct" apps such as Photos and iTunes to "reference" the HDD for the library (they will "look to" the same drive the app is on by default).
The large libraries don't "need speed" -- they can run just as well when "left behind" on the HDD.
The goal is to keep the SSD "lean and clean" so it will performa at its best.
Do it this way and I predict that you'll be very pleased with the results.
