I was choosing between Crucial M4 256GB and Seagate XT 500GB.

Crucial M4 is about 4 times as expensive, while offering about half the capacity.
Or in cents per GB:
Crucial M4: 136 cents per GB
Seagate XT: 18 cents per GB
(europe)

Now here's how the Seagate XT performs in real life inside my MBP 2011:

If you watch the video you'll see my usage and why the XT performs nearly the same as an SSD. This is the reason I choose the Seagate XT. I am aware that the SSD has some other advantages (better shockproof, longer battery life) but the large premium over the XT isn't worth it in my opinion.

I'm not sure if I understand correctly but I think you just compared a SATA III SSD to a to a mechanical HDD.

Different class of products, really. The Seagate XT, as good as it is, is at the end of the day a hard drive with a big cache that you have no control over.

I know. If you check the video you'll see that for my usage the XT performs the same as an SSD.
 
Different strokes for different folks.

I don't need gobs of storage on my laptop (getting a NAS for that ;) ) and so an SSD is a better fit. I like the idea that it has no mechanical moving parts and its much much quicker with the SSD installed :)
