While I would not really recommend it, yes you can RAID two different drives either RAID 0 or 1.

Of course your chance of an array failure in RAID 0 is increased, so be diligent in your backups.

I would not do this except for possible a RAID 1 for redundacy and only if the controller supports TRIM passthrough. Even then, you're better off just imaging the drive to a traditional HDD for backup. A RAID 0 of 2 different SSDs could theretically end up being slower than the faster of two, especially if your RAID controller does not support TRIM passthrough. This will also drasitcaly increase the likelyhood of dataloss.

Yes you can. No, you should not.
If you need the extra size (RAID0), you are much better off installing specific programs to the non-boot SSD as the D drive.
If you want the extra protection of RAID1, back-up your system drive regularly. Test that you can boot from a restore of the backup. Keep your data on the HDD so that restoring the OS backup will not lose your data.

RAID1 is not a substitute for backups.

ok ok no raid got it!! Ill use one 64gb ssd to boot off of and i just bought a new 256gb samsung to fill with programs and whatnot. So how during my pc build, how would i go about installing the drives as such? Do i just plug and assign drives? Or should i load the os onto the boot drive and after plug in the next drive and let it be discovered then assign..?
Sad part is my 64gb is 1st gen (micro center) ssd and the new one is... well a samsung 830 series ><.

Plenty of guides in the sticky at the top. The initial install of the OS should be done with only the OS drive attached to the machine. That can be the newer SSD if you like.

I would just go with your new samsung as your os drive if I where you. Especially if it's an 830 or 840 pro
