I am building a new pc soon and have decided to buy the OCZ Vertex 4 256gb SATA III SSD. Other than the OS and a few programs, I am using most of the space for games. I have a 7200rpm 500gb HDD for the rest of my games that I can't fit on the SSD. What I was wandering is should I put the two drives in a raid setup? Would that give the HDD better speed? I really don't know much about raid setups, I read something about putting them in a raid 0 setup. Whats the optimal configuration for this?
P. S. I also have a external HDD 500gb (USB plug and play) and a 1tb internal HDD both for storage and backup, if that makes any difference. Thanks.
In short -- No. Doing so would cripple your SSD, which is a nice big one that will hold a ton of applications besides the OS.
SSD caching for a HDD is for those who cannot afford a real SSD (like yours), meaning the 20-30gb size SSDs that can't hold much more than just an OS. Since memory is cheap, use a lot and then put your paging file on a HDD, since it will rarely be accessed. Look at the SSD optimization guides around here, or this one that is pretty good: http://thessdreview.com/ssd-guides/optimization-guides/...
Also, make sure that AHCI mode is selected in your BIOS as the SATA mode prior to installing Windows -- and do the install with only the boot SSD attached to insure that the SRP ends up on the SSD.
