HI, I have 3 x WD 500 AAKS drives I thought might go well as RAID 0 for my next build. Simply put, is 3 drives 50% faster than 2 drives in RAID 0? Or is there diminishing returns for RAID 0? Worth my while going 3 drives?? I have plenty of space in my stacker case. Any advice? Also, given these drives are now about 3 years old, would 1 x newer WD Black for example be faster than RAID 0 for these older drives? Cheers.
