Worth upgrading from SATA2 Intel 320 SSD to SATA3 Crucial M4 SSD?

There's more to an ssd than just how fast Windows loads. What about real world performance using real world applications? Doesn't that matter too? That puts the entire situation in a new light. With modern ssd's the general rule of thumb is go for a larger capacity instead of synthetic benchmark performance. Those benchmarks are called synthetic for a reason. They are not real. They do not accurately portray real world performance. At best they are a way to grossly exaggerate minor differences. Companies pick and choose different synthetic benchmarks to make their ssd's look good.

Here are three articles Tom's Hardware published that you might want to look at.
