Anandtech took the trouble of doing that: http://www.anandtech.com/show/4902/intel-ssd-710-200gb-review I think the main advantage of the 710 compared to the 320 is its much heavier over-provisioning and better quality MLC-chips. Both the 320 and 710 use the same controller and offer similar performance. But 320GB of raw capacity is sold as a 300GB Intel 320 and as a 200GB Intel 710... So if you don't need write-endurance, you can probably assume the 320 will be more capacity and bang for the buck and will be good enough. If you're a worried about write-endurance, you should have a look at the 710. You can obviously also only provision about 200GB of that 300GB 320-ssd and thus increase its expected live span, but you'd still miss the higher quality MLC. Given the fact that you can get two 320's for the price of one 710, its probably always a bit difficult to actually make the choice (unless you want a fixed amount of disks and the best endurance possible for that).
