Hey all thanks for reading this and helping me. I have never used RAID1 so two identical drives mirror eachother thus your transfer rate becomes 150 when it was 50mbps and we know SSD are 250mbps. Im excited about using this tehcnology and doing RAID1 on two WDC black 500GB . Once I do this then Im going to restore my image I created with W7. Soo then I format these two drives after choosing to go RAID1 in BIOS. Then when install begins IM guessing both drives will get data written on it at same time ? Am I right on that. Im looking for a speed boost in HD ... cuz I really need it,, I use DAW this will help boot times and overall hd speed. Will the C and D become one C or will I see in windows the C and the D in raid1 and another seperate non raid drive E. Thanks for all your answers and input and commenting on this. GG and of course GB
