I never ever knew you could use both the ssd for cache and the hdd for storage.
SSD to have OS and HDD to hold games.
How do i do that? I have an 64gb crucial ssd(they are my masters) and 1tb hdd.
my computer right now has 1tb how do i combine the ssd into this setup? is it possible or do i have to re install OS on both HDD and SSD?

You should leave your system the way it is currently set up.

If you want to use your SSD as a cache drive then your O/S has to be on your HDD, not your SSD.
If you use your SSD as a cache drive then the SATA ports your SSD & HDD are connected to have to be in RAID mode. You don't create an actual RAID-0 array.

You should never create a RAID-0 array with a SSD and a HDD. The RAID-0 array should be all SSDs or all HDDs.

The Read/Write performance of a RAID-0 is based upon the drive in the array with the slowest Read/Write speeds. So if you RAID-0 a SSD and a HDD you're not using the fast speeds of the SSD that you bought it for.

The total capacity of a RAID-0 array is based upon the drive in the array with the...

If you have an SSD, you don't want to Raid 0 it with a HDD. You'll actually slow down the performance of the pc for the OS and any games that could be installed solely on the SSD. Plus you'll only end up with a 120gb "drive". You just install the OS onto the SSD(as your boot drive) and maybe a game or two, and put all of your other storage on the HDD, plus any other games. You'll get the snappy response time for your OS and those games while still maintaining enough room in your computer for storing anything else.

The total capacity of a RAID-0 array is based upon the drive in the array with the smallest capacity. So if you RAID-0 a 64GB drive and a 1TB drive then your RAID array's total capacity (before formatting) will be 128GB (64 x 2).

I wanted the same thing your asking for, so I get your question. Really just install OS to SSD, install all games to HDD. You will keep having to MANUALLY select the location, and you need to do a bunch of tweaks like turn off SWAP FILE on the SDD, mapping in any programs preference to the D drive (especially CACHE / LOG files) etc. It take alot of constant management but I do love my 30 second reboots and loading most games in just under 1 minute (BF3, Crysis2, etc.).

How do you set your SATA ports with an SSD and HDD to 'RAID mode' without creating a RAID-0 array?

SATA ports can have 3 settings (modes): IDE, AHCI, & RAID.

Go into your motherboard's BIOS and there you will be able to change SATA modes.
Read your motherboard manual for instructions on how to enter BIOS and change SATA modes.

1) you DO NOT want to do that for the SSD, this will actually cause performance degredation unless your using RAID-3+ with multiple SSD drives.
2) You have to use RAID-0 if the drive is set to RAID, but that means either both drives are seperate or you combined them (normal process especially if all you do is 'click next'). The problems are
A) you get both combined BUT you do NOT 'speed up the HDD', but actually SLOW DOWN the SSD
B) something hiccups and the RAID breaks you lose everything across all drives.
3) RAID provides no benefits in your situation, unless your going to use multiple SAME type drives collectively together and need redundancy in case of failure. Also this would require a HEAVIER PSU to support all this additional workload.
