A single SSD will destroy any mechanical drives in RAID.
I appreciate the reply. Basically what Im doing is I'm setting up a RAID in a new Mac Pro for the purposes of video editing. That being said if money is no issue, I'm simply better off with SSDs then I am a HDD RAID. And considering an Apple RAID card is near 700$ for the card ALONE, it almost makes more fiscal sense as well
I am not that familiar with Apple and how they handle SSDs. Windows 7 has TRIM support that makes the drive last longer than if it was in RAID. RAID will still increase performance but at a cost of lifespan.
