Why is it pointless? two ocz vertex 2's in a raid 0 array is only £120! What's point in getting say 16gb of ram and a top spec i7 if the hdd can't keep up with the rest of they system?
1. because its for a 15 year old
2. because its to play games on, for which a sata-3 ssd is more than capable of all by its self.
3. the gains that would be seen to the end user for the required purpose would be minimal.
4. more to go wrong
5. if needed, it can always be added at a later date.
