I want to set up RAID 10. I have two Western Digital 10K rpm drives (74Gb) and two Western Digital 7200rpm drives (80Gb). I am going to set up the two 10K drives as the stripped set and the two 7200 drives as the mirrored set.
My question is, will the 7200 drives have a detrimental affect on the 10K drives in terms of system speed?
Also, the motherboard (Abit IP35) has 6 SATA interfaces. 4 of these will obviously be taken up by the RAID 10 configuration, but can I attach optical drives to the other 2 interfaces?
