I have done some research and read that RAID 0 would give me the best performance. The HDD has a SATA 6 interface, which my motherboard supports, and the SSD Is SATA II. This is my motherboard if you need more info.
So my question is, would a raid 0 setup be the best thing for these two drives? Will I lose performance if I combine the two drives as one? I want to install the OS on the SSD, so will I be able to select the SSD if I set it up as raid 0? Also do I install the OS first then configure the hard drive array? I am new to all of this so I feel a bit lost.
1)With a RAID 0 setup, for any number or drives, the OS sees them as one single drive & writes the data by striping it across the drives. So after you configue RAID 0, you cannot select any single drive as boot drive, storage drive, etc
2)A RAID 0 setup works best for identical drives. Doing it with an HDD & SSD is definitely not recommended. If anything, your SSD will be severely bottlenecked. Why not install the OS & applications on the SSD & keep the HDD for storage? It will work just well.
